ROBUST CONTROLLER DESIGN FOR LINEAR SYSTEMS WITH PARAMETRIC AND DYNAMIC UNCERTAINTIES

Ladislav Harsányi - Mária Dúbravská

   The paper deals with the synthesis of a robust PID controller for uncertain linear continuous-time SISO systems with specified parametric and dynamic uncertainty. First, the robust controller design for parametric uncertainty is performed in the frequency domain, based upon necessary and sufficient closed-loop robust stability conditions. Then, applying the small gain, the stability of the closed-loop with dynamic uncertainty is verified. The design procedure is demonstrated on an example.

Keywords: parametric uncertainty, dynamic uncertainty, robust stability
