Implementation of Type-2 Fuzzy Controller in Matlab Software

Dominik Ireneusz, Flaga Stanisław

Advances in Science and Technology. Research Journal

Vol. 17, no 5

374--384

The purpose of this work is to create a Matlab toolbox that makes it easy and accessible to get acquainted with a novel control method called type-2 fuzzy controller. A toolbox for working with type-1 controllers can be found in the Simulink package, while there is only few, simple toolboxes for type-2 fuzzy controllers. The article describes the details of the created software, which allows you to work both with simulation objects, but also enables you to create program code for an PLC industrial controller. This gives you the opportunity to work in a simulation environment with a model of the control object and then, after tuning the controller, to automatically implement the controller to control the real object. In the literature, you can find many methods for reducing type-2 to type-1 fuzzy logic, but most often they are compared to several well-known classical reduction methods, such as the KM algorithm. There is no compilation of the most popular methods and a comparison of their performance. With the new toolbox it was possible to quickly create and add new reduction methods so in the article an analysis of 16 reduction methods is also presented.

Demonstrator of a Digital Twin for Education and Training Purposes as a Web Application

The concept of Industry 4.0 has now become a fact. One of its key technological solutions – the digital twin – serves as a bridge between the real and virtual worlds. Designs for both products and tools to make these products are generated in the virtual world. Thanks to the simulation capabilities of these digital replicas, it is possible to eliminate design flaws well before the creation of physical prototypes. Thus, the question naturally arises as to what degree these mathematical models of objects, processes or services replicate their physical counterparts. A correctly generated digital twin is not only a model or visualisation of its counterpart; it also reflects its dynamic behaviour. The issue of digital twins is a very broad one, and currently on the market, there are appearing an increasing number of tools available for the development of these twins. More and more often, 3D modelling software can be integrated with a control system model, facilitating the testing of newly designed objects in the virtual world. This paper presents the concept of building simplified digital twins in a web application environment. In addition to educational usage, the presented idea should find application in the design of small production lines, significantly affecting the cost of producing a digital twin.
