Abstract

The H_∞ switching robust control problem for a class of uncertain fuzzy system is studied. Finite fuzzy state feedback controllers are provided in a given set of controllers, and the gain matrix of each controller is known. Though none of the individual controllers can make the systems stable with H_∞ disturbance attenuation, using single Lyapunov function and multiple Lyapunov functions technique the switching law is designed, such that the H_∞ control problem is solvable through design switching laws. Simulation results show the effectiveness of the design method.
