Abstract :
This paper studies a class of switched Linear Parameter Varying (LPV) systems in which different control faults are modeled as different system modes according to parameter varying. Two methods are proposed based on the hysteresis method of Multiple Lyapunov function, and H∞ state feedback and output feedback controllers are designed respectively by solving Linear Matrix Inequalities (LMIs). The method is applied to an attitude control model in a microsatellite, and simulation result verifies effectiveness of proposed methods.
