Wavelet networks are used to approximate to the α integral inverse system of a class of nonlinear continuous systems. Then the internal model control based on inverse system method is proposed for the combined pseudo linear system. Stability and robustness of the closed loop system are proved, and its performances are analyzed. Simulation results show that the method has better performance, high accuracy and simple design.
