Output Feedback H∞ Control for a class of Switched Fuzzy Systems Based on LMI

By switching technology, the problem of output feedback H-infinity control based on uncertain switched fuzzy system is considered. Using the multiple Lyapunov function methods, sufficient conditions based on for asymptotic stability on account of linear matrix inequality (LMI) are presented. Output feedback controllers are designed, which switch between the pointing some output feedback controllers. Moreover, switching strategy achieving system global asymptotic stability of the system is given. Moreover, switching techniques are used to derive the criteria, some subsystems are allowed to be unstable. A comparing simulation demonstrates the feasibility and the effectiveness of the proposed method.
