摘要: 考虑传感器到控制器通道上时延和丢包的非均匀分布特性,建立了基于多包传输的连续时间网络控制系统模型.通过定义Lyapunov泛函,并应用Jensen不等式,提出了具有非均匀分布的时延和丢包的网络控制系统镇定控制器设计方法;同时将该结果扩展到控制器到执行器通道存在非均匀分布时延和丢包的网络控制系统中.对于传感器到控制器通道和控制器到执行器通道同时采用多包传输的情况,本文提出的控制器设计方法依然可行.数值例子验证了本文给出的控制器设计方法的有效性.

Abstract: Considering the nonuniform distribution characteristic of networkinduced delay and packet dropout in a sensortocontroller channel, a new model is established for multiple packet transmissionbased continuoustime network control systems (NCSs). Then, by defining a new Lyapunov functional and using continuous Jensen inequality, the stabilizing controller design method is presented for the considered NCS. The result is also extended to NCSs with nonuniformly distributed controllertoactuator delay and packet dropout. Even for NCSs with multiplepacket transmission in both sensortocontroller and controllertoactuator channels, the proposed controller design method is still applicable. A numerical example is given to illustrate the effectiveness of the proposed method.

Key words: networked control system(NCS), multiplepacket transmission, delay, packet dropout, nonuniform distribution
