| 摘 要： | 针对含有未建模动态的非线性系统,结合非线性动态逆和小波网络提出了一种新的非线性控制方法。根据小波网络的逼近特性,利用具有在线学习能力的单隐层小波网络来补偿动态逆的误差,建立了基于自适应小波网络的控制结构,用李雅普洛夫函数导出了小波网络权值的自适应调整規则。通过自适应调节,使控制系统能对受控对象及时地作出反应。最后分析了小波网络的结构和输入。

| Abstract: | A novel nonlinear control algorithm using inverse dynamic and wavelet net is presented to nonlinear system with unmodeled dynamic. According to wavelet net approximation performance, the system modeling error is compensated by single hidden layer wavelet net which is capable of on-line learning. A control structure is built using adaptive wavelet net. A stable weights of wavelet net adjustment rule is derived using a Lyapunov function. The inputs and structure of wavelet net are discussed. |
