An adaptive control strategy for nonlinear systems is presented. The simple control law is derived based on minimizing a well-chosen performance index. Wavelets neural network model is applied to the scheme that can overcome the problem caused by the local minima when training the neural network. Compared with existing algorithms such as stochastic gradient algorithm, the present algorithm has the advantage of rapid convergence and low computational cost. The proposed approach is finally applied in a chemical reactor control problem. The simulation results proved that the proposed adaptive control method can effectively control unknown nonlinear systems.
