摘　　要：为弥补单端事件触发机制未考虑控制器与执行器间网络资源不足的限制,利用两个相互独立的事件触发器构建双端事件触发机制,针对离散不确定Markov跳变系统设计一种动态输出反馈控制器,结合双端事件触发条件建立网络化控制系统。然后,根据线性不等式技术推导出闭环控制系统随机稳定且满足H_(∞)性能指标的充分条件,利用奇异值分解法得到动态输出反馈控制器参数。最后,在系统具有双模态跳变情况下给出仿真算例,体现出所设计方案的有效性。For purpose of making up for the limitation that the single-terminal event triggered mechanism doesn’t consider the limitation of insufficient network resources between the controller and the actuator,making use of two mutually independent event triggers to construct a two-terminal event-triggered mechanism was implemented,including designing a dynamic output feedback H_(∞)controller for the discrete uncertain Markov jump system,and having the two-terminal event-triggered conditions considered to establish a networked control system and then,according to the linear inequality technique,the sufficient conditions for the closed-loop control system’s stochastic stability and satisfying the performance index were deduced,including having the singular value decomposition method adopted to obtain H_(∞)parameters of the dynamic output feedback controller.Finally,a simulation example was presented to demonstrate effectiveness of the designed scheme when the system has bimodal jumps.
