利用模糊决策实现变结构控制系统中的平滑过渡

Using a fuzzy decision to realize smooth transition in a variable structure control system

针对变结构控制中在切换面上存在抖动的问题,提出一种利用模糊集理论来实现变结构控制的平滑过渡的新方法。该方法消除了切换面上的抖动,且方法简单、有效,对解决与模态转换过程中有关的过渡问题有一定的启发作用和实际意义。

In view of the shake-defect on a switching surface in the variable structure control, this paper proposes a new method which uses a fuzzy set theory to realize a smooth transition in the vafiahle structure control. This method can eliminate the shake on the switching surface. It is simple and effective and has a certain heuristic and actual sense to solve the transition problem about the mode transform.
