| 摘 要： | 对一类有界的不确定的非线性动态系统 ,提出了一种基于具有连续函数特性的准滑动模态变结构控制的自适应控制方法。该方法在对象参数未知的情况下 ,利用变结构原理来学习在 L yapunov意义下系统的不确定界 ,从而实现对系统参数未知界的估计 ,并确保跟踪误差满足预先给定的性能要求。仿真结果表明该方法是有效的 ,并且使系统的抖振有较大程度的削弱

| Abstract: | A pseud sliding mode variable structure with continuous function based adaptive tracking control is proposed for a class of nonlinear systems with uncertainty bounds. In this scheme, the theory of variable structure control system with sliding mode is used to adaptively learn system uncertainty bounds in the Lyapunov sense so that the scheme can be utilized to approximate the uncertainty bounds without knowing the parameter of the object and an expected transient and steady state performance index for tracking errors can be achieved. Simulations for a second order system shows that the scheme is valid and the chatter can be eliminated considerably. |
