事件驱动控制系统下的新型触发机制

New Triggering Mechanism for Event-driven Control System

基于绝对触发机制,提出了一种混合触发机制用于分析事件驱动控制系统。首先,在绝对触发机制中加入相对触发条件,构建触发机制。其次,通过一个时延模型来表示事件驱动的触发机制,并引入一个调谐参数和一个加权矩阵用来消除控制器、输入矩阵和输出矩阵之间的耦合。再次,通过一定的理论推导,利用Wirtinger不等式和线性矩阵不等式(LMI)证明了闭合系统是稳定的,并最终指数收敛于一个有界区域。最后,仿真结果说明了所提方法的有效性。

A hybrid triggering mechanism based on absolute triggering mechanism is proposed in this paper for analyzing event-driven control systems.Firstly,the relative triggering conditions are added in the absolute triggering mechanism to complete the construction of the triggering mechanism.Secondly,the event-driven triggering mechanism is represented by a delay model,and a tuning parameter and a weighting matrix are introduced to eliminate the coupling between the controller,the input matrix and the output matrix.Thirdly,the Wirtinger inequality and the linear matrix inequality(LMI) are used to prove that the closed system is stable and converges exponentially to a bounded region through certain theoretical derivation.Finally,the simulation results show the effectiveness of the new method.
