摘　　要：针对通信受限的非线性网络控制系统,为兼顾系统性能和节约利用网络资源,引入事件触发通信机制(ETCM),利用时延建模方法和并行分布补偿(PDC)技术,将连续控制系统建模为一个采样数据误差依赖的非线性网络化系统模型;构建保守性低的时滞依赖和模糊基依赖的Lyapunov-Krasovskii泛函,给出增广系统稳定性和鲁棒性结果,得到鲁棒控制器存在的充分条件,提出一种基于线性矩阵不等式(LMIs)的事件触发参数,以及全局模糊L 1动态输出反馈控制器参数的协同设计方法。采用永磁同步电动机模型仿真验证,结果表明该设计方法可减少网络资源占用,达到闭环控制系统的性能要求。The event triggered communication mechanism is introduced for nonlinear NCSs with communication constraints,which intents to maintain the system performance and save network resources,and the continuous control system is modeled as a nonlinear NCSs with sampled-data error dependence by using time delay modeling method and parallel distributed compensation(PDC)technology.The delay-dependent and fuzzy basis-dependent Lyapunov-Krasovskii functional with low conservative is constructed,results on stability and robust of the augmented system are given,the sufficient conditions for the existence of robust controllers are obtained,and a collaborative design method based on linear matrix inequality(LMIs)for event triggered and global fuzzy L_(1)dynamic output feedback controller parameters is proposed.The simulation verification using a permanent magnet synchronous motor model shows that the proposed design method can reduce network resource consumption and meet the performance requirements of closed-loop control systems.
