摘要
讨论一类具有不确定性未知范数上界的线性系统 ,设计一种自适应近似变结构控制方案 ,对不确定性的未知范数上界进行实时在线估计 ,使所得系统在有限时间内到达滑模带 ,利用 Lyapunov直接方法证明系统是一致最终有界 ,同时设计的控制器是连续的。
The control problem for a class of linear systems with unknown upper norms of uncertainties is investigated. The proper switching function is firstly chosen such that the obtained sliding mode motion is stable,Then, the self-adaptive variable structure controller(VSC) for the upper bounds of uncertainties is presented. Furthermore, the controller is modified and proposed to guarantee uniform ultimate bound (UUB) of the systems states. Also,simulation result is presented to illustrate the features of the adaptive control strategy.
