摘要
基于变结构控制理论,提出一种用变结构控制方法来消除参数不确定性对系统性能的影响。首先建立延迟为τ的系统模型,鉴于该系统具有稳定与非稳定因素,我们制定一系列标准,从而写出系统的滑动模运动方程,经过证明,确认系统模型在所给的控制律下能顺利进入滑模区域,且处于该滑动切换面之下时,控制状态是稳定的,因此达到了设计要求。经实验证明,该滑动模控制器具有普遍性。
According to the variable structure control theories, this paper shows us a method that canceling influence of parameter indetermination. Firstly, build up a system model with delay, Then we establish a series criteria owing to that the system have steady and unsteady, get the sliding mode function. With the proof in this paper, we can see the system is invariant on the sliding surface. The control the appearance is stability, therefore the design of this sliding mode controller is Successful. By the proof of experiments, this controller could be fit almost all conditions easily.
