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.
