摘要
对基于事件触发机制的网络化Markov跳变系统的H_(∞)异步控制问题进行研究.通过引入事件触发机制减少控制信号的传输频率,从而降低通讯消耗.所设计的控制器与模态相关,与原系统异步,其异步关系采用隐Markov模型描述.采用增广向量方法得到闭环系统模型.利用Lyapunov函数方法和矩阵不等式技术,得出使闭环系统随机稳定且满足一定H_(∞)噪声衰减性能的充分条件,并进一步给出控制器增益求解方法.通过数值例子仿真验证结论的有效性.
This paper mainly investigates the H_(∞) asynchronous control problem of networked Markov jump system based on event-triggered mechanism.The event-triggered mechanism is introduced to reduce the transmission frequency of the control signal,so as to reduce the communication consumption.The designed controller is pattern-dependent and asynchronous with the original system,and its asynchronous relationship is described by a hidden Markov model,and the closed-loop system model is obtained by using the augmented vector method.By using the Lyapunov function method and matrix inequality technique,the sufficient conditions for the closed-loop system to be randomly stable with a certain H_(∞) noise attenuation performance are obtained,and the gain design method of the controller is provided.Finally,a numerical example is given to verify the effectiveness of the results.
