| 摘 要： | 针对一类含有未建模动态和未知控制增益符号的非线性系统,提出了一种输出反馈自适应跟踪控制方案.首先利用Kreisselmeier观测器实现了不可测状态的估计,在此基础上以回归设计方式设计了输出反馈动态面控制系统,通过引入Nussbaum函数解决了控制方向未知问题.该方案解克服了传统反推控制方法中的微分爆炸现象,并且所有未...

| Abstract: | An output feedback adaptive tracking control scheme is proposed for a class of uncertain nonlinear systems with unmodelled dynamics and unknown control gain sign.The unmeasurable system states are firstly estimated by using Kreisselmeier observer,then output feedback dynamic surface control system is designed in recurrent fashion,unknown control direction is counteracted by utilizing Nussbaum function.Explosion of complexity inherent in traditional backstepping control is eliminated,and the update law of th... |
