Indirect adaptive fuzzy output feedback control for nonlinear MIMO system

The indirect adaptive fuzzy control scheme based on observer is proposed for a class of MIMO nonlinear systems whose states are unavailable. By applying "dominant input" concept and combining adaptive control, H/sup /spl infin// control with fuzzy logic systems, the output feedback control law and parameter adaptive law are derived .The whole control scheme can guarantee the stability of the closed-loop, and achieve H/sup /spl infin// tracking performance.
