摘要

本文提出了一类模糊控制单输入-单输出非线性时变系统的稳定性分析方法。在Lyapunov意义下进行稳定性分析，得到了足够的一致渐近稳定性条件，可用于Takagi-Sugeno模糊控制器的设计。利用二次正定李雅普诺夫函数候选函数。通过设计FLC控制非线性对象的实例，验证了稳定性分析方法的有效性。

Stability analysis approach to a class of fuzzy controlled nonlinear time-varying systems

A stability analysis approach a class of fuzzy controlled Single Input-Single Output nonlinear time-varying systems is proposed in the paper. The stability analysis is done in the sense of Lyapunov resulting in sufficient uniform asymptotic stability conditions to be used in the design of Takagi-Sugeno fuzzy logic controllers (FLCs). Use is made of quadratic positive definite Lyapunov function candidates. An illustrative example validates the stability analysis approach by the designing of the FLC to control a nonlinear plant.
