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.
如何在信道約束下設計控製器對于網絡控製繫統的研究具有重要意義,為此提齣將脈遲控製思想應用于網絡控製繫統,通過減少反饋過程的通信次數來降低控製策略對信道傳輸能力的依賴.首先構建網絡脈遲控製繫統模型;繼而利用Lyapunov函數方法得到一類帶有隨機、有界時滯的網絡控製繫統的指數穩定性條件,併給齣瞭脈遲控製器參數與繫統收斂速度之間的定量關繫;最後通過數值倣真結果驗證瞭所提齣方法的有效性.

How to design an effective controller under the communication constraint is an important problem in networked control systems(NCSs). Therefore, impulsive control is applied to NCSs which can reduce the communication constraint for its less communication frequency. Firstly, a NCSs model based on impulsive control is proposed. Then by using Lyapunov function, an exponential stability criteria for a class of NCSs with bounded and random delay is established. The relation between convergence rate and controller’s parameters is also presented. Finally, simulation results show the effectiveness of the proposed method.
