网络化控制系统的时变采样及反馈调度策略
Strategy of time-varying sampling and feedback scheduling for networked control systems
摘要
Abstract
In multi-precessor networked control systems,time-delay of information-transmission is one of the main causes for bad control performance.Improved mixed traffic scheduling algorithm can cut much time-delay by sampling several times in a basic sampling-period and completing time-varying sampling-periods to shorten deadline of information-transmission.And by regulating the basic sampling-period of control system, feedback scheduling model for networked control system can schedule instantly information-transmission and always keep reasonable leisure-time.As a result, time-delay for information in the network is decreased, and a rate of utilization for network is raised.According to the results from simulation experiment, the rate of utilization for network and dynamic performance of networked control systems are all improved.关键词
