Abstract—This paper proposes a new method to design a fuzzy adaptive controller for a class of multi-input multi-output (MIMO) non-affine nonlinear systems in which functions of the systems are unknown. The lyapunov stability of the closed loop system is guaranteed. The proposed controller is robust against uncertainty and external disturbance. An illustrative example shows the effectiveness of the proposed method and the simulation results are very promising.
