摘　　要：本文研究了前提不匹配的区间2型(IT2)模糊系统的事件触发预测控制问题.首先,提出了一个IT2模糊系统模型,包括动态事件触发机制(ETM)和预测控制器,ETM可以通过减少传输的数据包数量来节省有限的网络资源,预测控制器可以预测两个成功传输时刻之间的系统状态来处理不可靠的通信网络.其次,根据李雅普诺夫稳定性理论和前提不匹配方法,得到了系统稳定的充分条件.然后,根据线性矩阵不等式(LMI)得到控制器增益.最后通过数值模拟验证了方法的有效性.This paper investigates the dynamic event-triggered predictive control problem of interval type-2(IT2)fuzzy systems with imperfect premise matching.First of all,an IT2 fuzzy system is proposed,including a dynamic event-triggered mechanism(ETM)that can save limited network resources by reducing the number of data packets transmitted and a predictive controller that can predict the state of the system between the two successful transmitted instants to deal with unreliable communication networks.Next,according to the Lyapunov stability theory and imperfect premise matching method,the sufficient conditions for system stabilization are obtained.Then,the gain of the controller are obtained by using linear matrix inequality(LMI).Finally,the validity of the design method is demonstrated by the numerical simulation.
