ROBUST OUTPUT FEEDBACK QUADRATIC CONTROLLER DESIGN

Ľubomír Grman - Vojtech Veselý

   The paper provides a survey of some recent quadratic stability methods for static output feedback robust controller design for linear continuous-time invariant systems with convex polytopic uncertainty and their mutual comparison. Robust controller design is based on linear matrix inequalities (LMIs) conditions and single Lyapunov functions. The presented quadratic stability methods are compared on numerical examples and randomly generated ones and it is shown which of them provides the least conservative results.
