Abstract :
This paper presents a fuzzy variable structure controller for MIMO systems. Motivated by the principle of variable structure control strategy, a systematic design procedure is proposed. The proposed fuzzy controller is constructed to approximate the unknown system and to reduce the chattering phenomenon. The controller parameters can also be adapted online to utilize the control energy more efficiently. The simulation results show that the proposed control algorithm exhibits strong robustness against model uncertainties and external disturbances
