本文研究控制存在时滞的线性系统的变结构控制问题,指出传统的切换函数在时滞系统中应当是一个切换泛函。在系统绝对能控的条件下,给出了具有稳定滑动模态的切换泛函的设计方法。利用趋近律概念给出了相应的变结构控制器。
In this paper, we study the control of variable structure of linear systems with time-delay, and point out that the traditional switching function should be a switching functional in time-delay systems. Under the condition of the system being absolutely controllable, a design method of switched functional with stable sliding mode is given. The corresponding variable structure controller is given by using the concept of approach law.
