Tracking and stabilization are two typical problems of chaotic system control. A unit error model is built for the above both two problems and a kind of adaptive control is designed to solve a special kind of system uncertainty. The uncertain nonlinear function. Is not required to be bounded compared with a known smooth positive function. Also a kind of approximation method is proposed for nonlinear functions based on Fourier series method. At last, a four dimension chaotic system is taken as an example to do the numerical simulation to testify the rightness of the proposed method.
