如何在信道约束下设计控制器对于网络控制系统的研究具有重要意义,为此提出将脉冲控制思想应用于网络控制系统,通过减少反馈过程的通信次数来降低控制策略对信道传输能力的依赖.首先构建网络脉冲控制系统模型;继而利用Lyapunov函数方法得到一类带有随机、有界时滞的网络控制系统的指数稳定性条件,并给出了脉冲控制器参数与系统收敛速度之间的定量关系;最后通过数值仿真结果验证了所提出方法的有效性. How to design the controller under the channel constraint is of great significance to the research of network control system. Therefore, the idea of ​​applying pulse control to network control system is proposed, and the dependence of control strategy on channel transmission capability is reduced by reducing the number of communication in feedback process. Then the exponential stability of a class of networked control systems with stochastic and bounded delays is obtained by Lyapunov function method. The quantitative relationship between the parameters of the pulse controller and the convergence rate of the system is given. Finally, the numerical simulation results verify the effectiveness of the proposed method.
