Syntéza nelineárních systémů řízení

Abstract

The thesis deals with Nonlinear Control Systems Synthesis. The problems of nonlinear systems are theoretically described in the introductory part, but main attention is given to the use of Hammerstein and Wiener models for properties description of nonlinear systems. Furthermore, the work shows how to use of System Identification Toolbox for determining Hammerstein and Wiener models in experimental identification. Toolbox functionality is verified with the chosen model. The next section describes selected approaches to nonlinear systems control synthesis and their necessary steps are demonstrated on the chosen model. The control design is verified by using digital simulation as well as on the real laboratory model. Results of simulations and real measurements are graphically processed, courses of variables are evaluated and also other directions for further solutions were suggested.
