Evaluation of the results of support for schools by manufacturing enterprises - a competence management aiding model

Szafrański Maciej

Management and Production Engineering Review

2022

Vol. 13, No. 2

102--116

Employers signal difficulties in sourcing technically-educated staff. They often engage, though to a limited degree, in cooperation with vocational schools to mitigate this difficulty. One of the reasons for the limited involvement of enterprises in cooperation with schools is the difficulty in assessing the benefits that it may bring. The aim of the study in the article was to develop and initially verify a model for evaluating the results of supporting secondary technical schools by manufacturing enterprises. The article features a multiple case study using several types of interviews, a distributed questionnaire and an analysis of secondary sources. The study was conducted in cooperation with four large manufacturing enterprises. The result of the research is a more thorough understanding of the possibilities and limitations in evaluating the results of support for schools. This support should translate in enterprises into more effective and efficient management of the competences of the future.

Design of optimal state feedback controller with observer for multidimensional electrical system

Piotrowski Robert, Szafrański Maciej, Żuk Konrad

Przegląd Elektrotechniczny

R. 96, nr 5

From the control point of view, two-input-two-output RC electrical system is a linear and multidimensional system. In this paper, integral control and closed-loop observer are verified whether they can be used and designed. To verify this, Kalman tests are made. These structures are presented and discussed. Integral Control is tested with some base disturbances impact and checked whether it can handle them. The estimated values from the observer are compared with the original states. Simulation tests and real tests of control systems are presented.

Z punktu widzenia sterowania, system elektryczny RC z dwoma wejściami i dwoma wyjściami jest systemem liniowym i wielowymiarowym. W artykule zaprojektowano sterowanie całkujące tym system wraz z obserwatorem dołączonym do układu regulacji. W pracy wykorzystano obserwator Kalmana. Przedstawiono testy symulacyjne i testy wykonanego systemu regulacji.
