| 摘 要： | 在基于IP网络的网络控制系统(NCS s)中,网络诱导时延变化显著且往往大于一个采样周期.本文引用数据通信中应用广泛的网络回程时间来估计NCS s中时变的全回路网络诱导时延,并提出了一种新的自适应Sm ith补偿器.仿真结果表明,该补偿器能够有效地消除网络诱导时延变化对控制性能的负面影响;结合该自适应Sm ith补偿器所设计的控制系统能够获得很好的控制性能与较强的鲁棒性.

| Abstract: | In networked control systems(NCSs) over IP networks,the network-induced delay often varies dramatically and might be longer than a sampling period.The concept of round trip time,which is widely used in data communication,is introduced to estimate the varying network-induced delay,and a novel adaptive Smith compensator is developed in this paper.Simulation results show that the proposed compensator can avoid the negative impacts of the varying network-induced delay on control performances,and the control system with the adaptive Smith compensator can provide good performances and strong robustness. |
