Sliding mode control for a class of uncertain distributed parameter systems with time-varying delay

研究一类不确定变时滞分布参数系统的滑动模控制问题.首先设计一种无记忆功能的变结构控制器;然后分析了在滑动模切换面上滑动模控制系统关于不确定量的不变性特征;最后给出了从任意初始位置出发的轨线到达滑动模态区的时间估计.研究表明,所设计的控制器结构简单,容易实现.

The sliding mode control problems of a class of uncertain distributed parameter systems with time-varying delay are investigated. A non-memory variable structure controller is designed. The invariant characteristic about uncertainties of the sliding mode control system on the sliding surface is analysed and the approximate time estimate from any initial state to sliding manifolds is obtained. Experimental results show the simple stucture and the feasibility of the proposed controller.
