模糊控制系统的稳定性

The Stability of Fuzzy Control System

与经典控制方法相比模糊控制的一个主要缺陷就是缺乏稳定性的证明。本文将模糊控制器的稳定性分析方法做一总结，重点在于确定各种稳定性证明方法中隐性和显性的假设与限制，并说明各种稳定性证明方法适用的模糊控制结构。本文还介绍了根据稳定性来设计模糊控制器的方法。

One of the main objections to fuzzy control compared to classical control engineering is the lack of stability proofs. The paper will give an overview of the existing methods for evaluating and testing the stability of fuzzy controllers. Special attention will be paid to the identification of the implicit and explicit assumptions and restrictions necessary for the various methods of stability proofs. It will be shown that the methods used for proving stability are especially suitable for a particular class of fuzzy controller structures. The method of design stabilized fuzzy controller is also introduced in this paper.
