| 摘 要： | 为解决反步法在虚拟控制求导时存在计算膨胀的缺陷问题,提出了一种自适应反步控制算法.采用CMAC神经网络在线学习系统不确定性以及各阶虚拟控制量的导数信息,从而避免了系统阶次较高时引起的计算膨胀问题,并且该控制算法在实际控制输入前加入低通滤波器,避免了不连续输入可能引起的抖振问题.Lyapunov稳定性分析表明,该控制方法...

| Abstract: | To solve the defects of the calculation expansion in the virtual control derivation,based on the CMAC neural network online learning system and the derivation information of the various orders virtual control variation,an adaptive back-stepping control algorithm was proposed in order to avoid the calculation expansion problem which caused by the high order of the system.The low-pass filter was added in this algorithm before actual control inputing to avoid the chattering problem which caused by the disconti... |
