摘要
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。
A stable wavelet network adaptive control scheme is proposed for a class of nonlinear systems with mismatched uncertainties. The scheme can effectively relax the usual two restrictions:1) The unkown nonlinearities should appear on the same equation as the control input; 2) A bound on the network approximation error should be known. The simulation shows that the new scheme is very effective.
