摘要
提出一类新型的切换模糊系统,即以聚类型模糊集合为基础的切换模糊系统.模糊模型的前件采用聚类型模糊集合和隶属度函数的形式.在研究中,首先讨论聚类型模糊集合的切换模糊系统形式和机理;然后,使用多Lyapunov函数给出离散切换模糊系统在满足最小驻留时间切换策略下的指数稳定性条件,并设计出切换律;最后,通过仿真实例验证所提出方法的有效性.
A new type of switched fuzzy system is proposed, which is based on clustering fuzzy sets. In the proposed fuzzy system, the premise part of the fuzzy model adopts clustering fuzzy sets and clustering membership functions.Firstly, the clustering switched fuzzy systems and the corresponding principles are studlied. Then, the multiple Lyapunov functions are used to confirm exponential stability conditions under the satisfying switched strategy of the minimum dwell time, and the corresponding switching law is designed. Finally, a simulation example illustrate the effectiveness of the proposed method.
