摘　　要：将一类非线性系统等价表示为时变线性系统,在此基础上设计了自适应控制器。利用小波网络直接辨识控制器参数。从理论上证明了闭环系统的稳定性。仿真结果表明了所提算法的有效性。The adaptive control was implemented for a class of nonlinear system by substituting it with a time-varying linear system. The wavelet networks were used directly to identify the coefficients of time-varying controller. The stability of closed-loop system was proved, and the effectiveness of the presented method was demonstrated by the simulation results.
