针对一类非匹配不确定性非线性系统，提出一种基于子波网络的稳定自适应跟踪控制方案；对子波网络逼近误差界进行自适应处理，不需要逼近误差界的先验信息。仿真结果表明所提出的方案是有效的。 Aiming at a class of non-matching uncertain nonlinear systems, a stable adaptive tracking control scheme based on wavelet network is proposed. The wavelet sub-network approximation error bound is adaptively processed without prior information about the error bound. Simulation results show that the proposed scheme is effective.
