基于控制器切换的一类不确定模糊系统的稳定性

Stability of a Class of Uncertain Fuzzy Systemsbased on Controller Switching

基于T-S模糊模型研究了一类不确定时滞模糊系统的稳定性问题。使用控制器切换技术及多Lyapunov函数方法,在已给定的平行分布补偿PDC控制器中,设计适当的切换律,使得相应的闭环系统渐近稳定。并通过仿真算例验证了设计方法的可行性和有效性。

The problem of stability for a class of T-S fuzzy time-delay systems was investigated . By using controller switching technique and multiple Lyapunov function method, in several proposed PDC controllers, an appropriate switching law was designed to ensure that the closed-loop system is asymptotically stable for all admissible uncertainties. A simulation result demonstrates the feasibility and the effectiveness of the designed method.
