Output tracking controller for non-affine nonlinear systems with nonlinear output: Fuzzy adaptive approach

In this paper, we proposed a new method of a fuzzy adaptive controller design for a class of non-affine nonlinear systems in which functions of the systems are unknown. The Lyapunov stability of the closed loop system, robustness against uncertainty and external disturbance, the convergence of the output error to zero and the boundedness of the internal signal are guaranteed. An illustrative example shows the effectiveness of the proposed method and the simulation results are very promising.
