基于改进Smith预估补偿的网络控制系统研究

Abstract

Abstract: In order to effectively restrain the impact of network delay on the NCS,a new approach is proposed that modifies Smith dynamic prediction compensation.The delays of forward path are removed from the closed loop,and time-variant uncertain return path(sensor to controller) delay is totally eliminated from the system.Therefore,the traffic on the return path does not need to be scheduled.Because this compensation model does not include network delays,thus network delays do not need to be measured,identified or estimated on-line,and it is applicable to some occasions that network delays are random,time-variant and uncertain,possibly large compared to one,even tens sampling periods.Based on network protocols of CSMA/CD(Ethernet) and CSMA/AMP(CAN bus),the simulation results show that approach is effective.
