摘　　要：本文针对一类含有执行器饱和的网络化切换模糊系统,在系统状态不可测的情况下,通过设计状态观测器来估计系统中的不可测状态变量,基于事件触发机制设计了观测器的控制器,用凸组合法来处理执行器饱和对系统性能的影响,并利用多Lyapunov函数理论和平均驻留时间方法证明了闭环系统的稳定性。数值仿真实例验证了提出方法的有效性。As for a class of networked switched fuzzy systems with actuator saturation, this paper designs the observer to estimate the state variables when the states of the system are unavailable? The controllers are designed based on the event-triggered mechanism and the convex combination method is used to deal with the influence of the actuator saturation. The exponential stability of the systems is proved by using the multiple Lyapunov function theory and average dwell time method. At last, a numerical example is provided to validate the effectiveness of the method.
