SYNTHESIS OF OPTIMAL CONTROL SYSTEMS WITH NONLINEAR ACTIVATION FUNCTION
Abstract:

Analysis of the current level of micro-electronics and power electronics development has shown the existence of the prerequisites for the development and implementation of new control algorithms. Development of new control algorithms is caused by the need to improve product quality while reducing its cost. One approach to the problem of production improving and technological process modernization is discontinuous control that is based on the use of first and higher orders sliding modes. Analysis of publications devoted to the creation and study of first and second orders discontinuous control systems has shown isolation of existing approaches and methods.

So the identification of the general relations, characterizing the functioning of discontinuous control systems, and development on their basis structural and algorithmic synthesis, is an urgent task.

This paper proposes the development of modal control method to the case of characteristic equation’s variables desired roots. Together with the feedback linearization, this approach allows to determine the parameters and structure of the controller through the desired characteristic polynomial coefficients and control object parameters.
