In general, fuzzy logic are able to handle several problems that classic logic is not cabaple, mainly due its capacity to represent the imprecision and uncertanty of human logic and reasoning. But, even classic fuzzy logic or type-1 fuzzy logic are not adquate to fully represent the human knowledge, so type-2 fuzzy logic is more suitable to solve this problem. Controllers based on those logic are known as type-1 and type-2 fuzzy controllers, these controllers are hard to tune due its large number of parameters. In literature, there are a lot of strategy to solve this problem for both controllers based on meta-heuristics. To investigate and validate the controllers obtained it was used a Servo motor from Quanser, a control problem which requires precision and velocity in error correction. We tested several controlers and optimization techniques based on classic PI controllers and particle swarm optimization, genetic algorithms and ant colony optimization based on three diferents avaliation index IEA, ITEA e Goodhard index. By analyzing the results obtained, the type-2 fuzzy controller showed significant gain for the control of this plant, when optimized with the PSO method. From the results, it can also be inferred that the ant algorithm was not suitable for this problem, with the proposed evaluation function.

W przemyśle kilka strategii i algorytmów sterowania jest już używanych i opisanych w literaturze. Wśród istniejących technik, regulatory rozmyte wyróżniają się zdolnością do radzenia sobie z poważnymi nieliniowościami występującymi w rzeczywistych instalacjach oraz zdolnością do reprezentowania wiedzy eksperckiej, która jest nieprecyzyjna i matematycznie niedokładna. W tej pracy zbadano dwa typy istniejących regulatorów rozmytych opartych na modelu Sugeno, są to rozmyte typu 1, tutaj sklasyfikowane jako konwencjonalne rozmyte i rozmyte typu 2. Analizując otrzymane wyniki, regulator rozmyty typu 2 wykazał znaczny zysk w sterowaniu t ˛a instalacją, gdy został zoptymalizowany metod ˛a PSO. Z wyników można równie ˙ z wywnioskować, że algorytm mrówkowy nie był odpowiedni dla tego problemu z zaproponowaną funkcją ewaluacyjną.

The screw feeder design for the pre-compaction of bulk materials to be briquetted in a roll press is considered to increase the overall reliability. The relationship between the parameters of the screw feeder and its technological characteristics is investigated by the example of two fine-grained materials. A new mathematical model and design algorithm have been developed, which takes into account the properties of materials, the roller press parameters, the shape of the briquettes, and their deformation after compaction. The relationship between the pre-compaction pressure and the material stack height at the inlet is determined. The relations between the torque, the screw pitch, and the material stack height above the inlet, as well as the drive power and the screw pitch on productivity, are investigated. In experiments, using the proposed design, the compaction ratio of the peat increases by 22-27%, and hydrolyzed lignin –by 14-17%. The proposed approach allows for preventing drive overloading and ensures the reliable operation of pre-compaction devices for the roller presses.

The article mentions a method of optimal design for the base network in horizontal displacement monitoring at hydroelectric works, based on the average residual level of the measured values. When the target function is the weakest positional error, the obtained result after optimizing is the unique plan that no depends on the designers and their experience. Thus, this is helpful for the production units because they no need to have experts in designing the network. Experiment for the base network of deformation monitoring at Song Hinh hydroelectricity shows that 44%, 50% and 60% of the initial measurement can be reduced when the average residual level is chosen 0.5, 0.4 and 0.3, respectively. The weakest position error of the network after optimizing is 2.4 mm, 2.5 mm and 2.6 mm, respectively, all are smaller than requirement ±3.6mm. This method is mainly applied for the side-angle network that was measured by total station, without considering the optimal design network in the priority direction.

Gdy funkcją docelową jest najsłabszy błąd pozycjonowania, uzyskany wynik po optymalizacji jest unikalnym planem, który nie zależy od projektantów i ich doświadczenia. Jest to więc pomocne dla jednostek produkcyjnych, ponieważ nie potrzebują one ekspertów do projektowania sieci. Eksperyment dla podstawowej sieci monitorowania deformacji w elektrowni wodnej Song Hinh pokazuje, że 44%, 50% i 60% początkowego pomiaru można zmniejszyć, gdy średni poziom pozostałości zostanie wybrany odpowiednio 0,5, 0,4 i 0,3. Najsłabszy błąd pozycji sieci po optymalizacji wynosi odpowiednio 2,4 mm, 2,5 mm i 2,6 mm, wszystkie są mniejsze niż wymagane ±3,6 mm. Metodę tę stosuje się głównie dla sieci kątów bocznych, które zostały zmierzone przez tachimetr, bez uwzględnienia optymalnej sieci projektowej w kierunku pierwszeństwa.

This paper presents a novel magnetic twisting device with a coaxial double rotor based on non-contact transmission characteristics of magnetic drive technology. When the twisting device rotates one cycle, the yarn can get triple twists. This means the new device can twist three times more than what the traditional single twist does. The structure of the magnetic twisting device is designed according to the twisting principle. The influence of main structural parameters on the magnetic torque is analyzed. To optimize the maximum transmission torque and the minimum magnet volume, the multi-objective optimization design model for the twisting device is established. Main parameters such as the relative angle of active disc assembly and passive disc assembly, the thickness of magnet, and the average radius of the magnet distribution are optimized by NSGA-II algorithm. Optimization results show that the proposed structural optimization design of a twisting device based on the magnetic drive has excellent performance and is effective for industrial application.

In this paper, several analytical models are presented for the optimal design of a trapezoidal composite channel cross-section. The objective function is the cost function per unit length of the channel, which includes the excavation and lining costs. To define the system, design variables including channel depth, channel width, side slopes, freeboard, and roughness coefficients were used. The constraints include Manning’s equation, flow velocity, Froude number, and water surface width. The Simultaneous Perturbation Stochastic Approximation (SPSA) algorithm was used to solve the optimization problem. The results are presented in three parts; in the first part, the optimal values of the design variables and the objective function are presented in different discharges. In the second part, the relationship between cost and design variables in different discharges is presented in the form of conceptual and analytical models and mathematical functions. Finally, in the third part, the changes in the design variables and cost function are presented as a graph based on the discharge variations. Results indicate that the cost increases with increasing water depth, left side slope, equivalent roughness coefficient, and freeboard.

The paper presents a methodology for the optimal design of multilayer thermal protection based on high-porosity open-cell foam, taking into account the foam morphology. The vector of design parameters includes the thicknesses of layers, porosity and cell diameter of open-cell foam and should ensure required operation temperature on the boundaries of layers and a minimum of the total mass of the system. The optimization problem is solved using a computational scheme, which combines the projected Lagrangian method with the quadratic subproblem and the penalty function method. The penalty function method provides a good initial estimate of the optimal parameters’ values for the projected Lagrangian method with excellent local convergence properties. To illustrate the implementation of the developed algorithm and the corresponding software, the problem of choosing the optimal layer thicknesses for the multilayer thermal protection of a spacecraft along with the cell diameter and porosity of foam is considered.

Optimal shapes in the class of polynomial functions for rotating annular disks with respect to the mixed creep rupture time are found. Two effects leading to damage: diminishing of transversal dimensions and growth of micro-cracks are simultaneously taken into account. The first of them requires the finite strain analysis, the latter is described by Kachanov’s evolution equation. Behaviour of the material is described by nonlinear Norton’s law, generalized for true stresses and logarithmic strains, and the shape change law in form of similarity of true stresses and logarithmic strains deviators. For optimal shapes of the disk, changes of geometry and a continuity function are presented. The theoretical considerations based on the perception of the structural components as some highlighted objects with defined properties is presented.

Based on the example of the development process of the cast suspension of a special-purpose vehicle the application of the integrated engineering design methodology (ICME – Integrated Computational Materials Engineering) and the development of construction has been presented. Identification of the operating and critical loads, which are guidelines for carrying out the structure strength shaping process, material and technological conversion, are due to the needs and requirements of the suspension system and the purpose and objectives of the special mobile platform. The developed cast suspension element construction includes the use of high-strength AlZnMgCu aluminum alloy. The properties of the used alloy and designed shape allows for the transfer of assumed operating loads in normal exploitation conditions and in the dynamic, critical loads to the susceptibility to damage in the assumed casting areas. For the proposed design, conducted numerical analyzes includes the impact of the shock wave pulse on the occurrence of the destructive stress fields. Based on their distribution, the areas of possible decomposition of the structure of the design element were estimated. The results allowed to devise an element with predicted destructions that allow to absorb a significant part of the impact energy of the shock wave front, which is also the buffer zone for the propagation of destruction for the critical kinematic nodes of the system.

The research and development of a rice rope laying machine (RRLM) provides new ideas for a design of a rice direct seeding machine, and solves existing problems encountered in direct seeding techniques currently in use. The RRLM has been developed based on an in-depth analysis of the design principles and main structure parameters of rice direct seeding machines. The completed machine consists of all necessary components including an anti-blocking device, sowing device, opening device, banking device, compacting device, etc. The optimal design of the parts and structure of the RRLM was completed using the three-dimensional Unigraphics NX (UG NX) software. The rationale and the performance of the machine and its components were analyzed using this virtual prototyping technology. The key technology problems commonly encountered, which included the opener being easily plugged up, the difficulty in adjusting/controlling the number of seeds per hole, and seeding rope easily broking during the process of laying, have all been effectively solved. The field test results have shown that this machine has the advantage of good maneuverability and high working efficiency, the reliability and quality of seeding rope placement meets (fulfills) the design requirements, the profiling and compacting effect of the machine is very good, and the uniformity of seeding depth and accurate rope placement are guaranteed.

The main aim of the paper is improved dynamic vibration absorbers (DVA) design, taking into account the complex rotating machines dynamics. It is often impossible to balance the rotating elements so as to reduce the vibration to an acceptable level. The paper considers the provision of DVA or number of such DVA. Such originally designed DVA reduces vibration selectively in the maximum mode of vibration without introducing vibration in other modes. The result is achieved at a far lower expense than would be required to replace the concrete and steel foundation with a more massive one. By installing DVA, one can minimize excitation virtually at the source. In order to be more effective, a vibration absorption system should react in all the frequency domains. The present absorber also has as an advantage that it can be constructed so that it has a wide-range vibration absorption property. This construction allows for an easy connection of the above rotor equipment. In order to determine the optimal parameters of DVA, the complete modeling of the rotating machine dynamics is obvious. The two degrees of freedom model are totally inadequate to accurately calculate the vibration frequencies of the construction and therefore, for a sufficiently accurate determination of its dimensional characteristics so as to determine such frequencies. It is therefore necessary in practice to dimension the construction through more complex modeling. In particular, concentrated mass and rigidity calculation methods may be adopted based on an even more accurate theoretical determination. The numerical schemes (NS) row is considered for the complex vibration-excited constructions. Methods of decomposition and the NS synthesis are considered on the basis of new methods of modal synthesis. Complex NS are obtained of discretely-continua type, which enables in the adaptive mode to calculate tension not only in the continuum elements, but in the places of the most tension concentration in joints. Traditional design methodology, based on discontinuous models of structures and machines is not effective for high frequency vibration. The present research develops a modern prediction and control methodology, based on complex continuum theory and application of special frequency characteristics of structures. Complex continuum theory allows to take into consideration system anisotropy, supporting structure strain effect on equipment motions and to determine some new effects that are not described by ordinary mechanics of the continuum theory. The absorbers in accordance with this paper may be applied not only to electric machines ore aeronautic structures, but also to any other type of vibration-excited structure, such as cars, chisel installation, optical, magneto-optical disks, washing machines, refrigerators, vacuum cleaners, etc.

The aim of this study is to find the cost design of RC tension with varying conditions using the Artificial Neural Network. Design constraints were used to cover all reliable design parameters, such as limiting cross sectional dimensions and; their reinforcement ratio and even the beahviour of optimally designed sections. The design of the RC tension members were made using Indian and European standard specifications which were discussed. The designed tension members according to both codes satisfy the strength and serviceability criteria. While no literature is available on the optimal design of RC tension members, the cross-sectional dimensions of the tension membersfor different grades of concrete and steel, and area of formwork are considered as the variables in the present optimum design model. A design example is explained and the results are presented. It is concluded that the proposed optimum design model yields rational, reliable, and practical designs.

The composite materials optimal design problem which taking into account the thermal characteristics is the part of an actual structural design task. A wide range of variety of such material structures and the complexity of modeling some physical phenomena (such as the phenomenon of those structures effective characteristics percolation threshold appearing) requires a high level of detail in physico-mathematical models. Here, in this paper, were analyzed the role and place of physico-mathematical microlevel models in problems of composite materials optimal design. The methods of such materials representative volume elements construction within the model calculations, which are the key step in the modeling of complex structures variety, also were analyzed. Basing on the usage of finite element method for modeling of stationary heat conduction and elasticity linear problems was proposed the combined formalization of coupled thermoelasticity problems simulation method in complex structured composite materials, which is especially useful when used in engineering applications which provide a high level of abstraction. Basing on the analogy method and theory of similarity were developed the complex structured composite materials microlevel models, which allow one to synthesize and then re-use in the problems of composite materials optimal design, such effective thermal characteristics as thermal conduction coefficient, Young's modulus, Poisson's ratio and temperature coefficient of linear expansion. This gives the ability to avoid of classical complex mathematical homogenization processes or real experiments. The method and models were successfully implemented by using of highperformance parallel and distributed computing technologies in heterogeneous computing environments, as evidenced by the simulation results.
