| 摘 要： | 对一类控制方向未知的时变非线性系统的控制问题进行了研究.首先,设计了一种迭代神经网络估计器,并通过推导得到了逼近引理,实现了对时变不确定性的逼近;然后,提出了用迭代神经网络逼近时变不确定性,用Nussbaum函数估计未知控制方向的总体设计思想.利用李雅普诺夫稳定性理论和自适应迭代学习控制技术设计了控制系统,并进行稳定性...

| Abstract: | A class of time-varying nonlinear systems with unknown control directions was researched.Firstly,an iterative learning neural network approximator(ILNNA) design scheme was proposed.Corresponding lemma was obtained to approximate time-varying uncertainties.Subsequently,an idea of using ILNNA to approximate time-varying uncertainties while using Nussbaum function to estimate the unknown control direction was aroused.The controller was designed by adaptive iterative learning control technique,and the stability... |
