Abstract: A new sliding mode control method is proposed for the problem of network-induced time delays in networked control systems. A discrete mode of networked control systems with the linear time-invariant plant is derived from fast output sampling. In terms of the mode, parameters of sliding mode plane are provided by pole assignment, and a new sliding mode control law using fast output sampling feedback is presented. Simulation results illustrate the effectiveness of the proposed control approach.

摘要： 针对网络控制系统的网络诱导时延问题，提出了一种新的滑模控制方法。通过快速采样被控对象输出，建立了具有线性时不变被控对象的网络控制系统的离散模型。在此基础上，用极点配置法给出了滑模切换面参数，设计了输出反馈离散滑模控制器。仿真结果验证了该控制方法的有效性。
