Adaptive fuzzy control for MIMO non-affine nonlinear systems
MIMO非仿射非线性系统的自适应模糊控制

For a class of multi-input multi-output(MIMO) non-affine nonlinear systems, an adaptive fuzzy H-infinity control scheme is proposed which combines the adaptive fuzzy control with the high gain observer. Based on the implicit function theory, the existence of an ideal non-affine nonlinear system controller, that can achieve control objectives, is firstly shown. A high gain observer is employed to obtain the unavailable states in measurement for constructing the output feedback controller. To achieve high precision, the adaptive fuzzy control scheme is designed for improving the approximation ability of the observer on-line. Finally, the simulation results are performed to demonstrate the superiority and the effectiveness of the proposed method.
