Robustness preserving interpolation of robust LQG controllers for gain-scheduling

This paper presents an interpolation algorithm for gain-scheduling of robust output feedback controllers for a class of uncertain linear parameter-varying (LPV) systems. The system under consideration is assumed to be uncertain for each instance of the scheduling variable. The aim is to generate a continuously varying family of controllers that preserve robust stability and also guarantee a certain level of robust performance of the closed loop system for all instances of scheduling variable.
