Control Theory 2
FEKT-BPC-RR2Acad. year: 2021/2022
Analysis and synthesis of advanced control systems, especially nonlinear, is discussed in this course. Basic methods for nonlinear systems stability analysis, state trajectory behaviour evaluation and nonlinear control design are presented. Methods for robust control design and system parameters estimation are also described.
Learning outcomes of the course unit
- analyse nonlinear systems behaviour
- design nonlinear control systems
- analyse stability of nonlinear dynamical systems
- design control algorithms based on linearisation techniques
- design control structures based on relay control and sliding mode control
The subject knowledge on the secondary school level is required. Knowledge of linear systems control (BRR1) and systems modeling (BMOD) is assumed.
