| 摘 要： | 基于网络化控制系统是具有延迟约束的实时系统，首先建立了保证网络控制性能的延迟约束模型，以此为基础提出满足上述延迟约束的带宽调度策略，以兼顾控制系统控制性能和网络系统服务质量；利用时间需求分析，给出在该策略下的周期、偶发与非周期等３种网络数据的可调度条件及延迟估计的算法，给出调度策略与保证网络控制性能的协调优化设计方法；最后提出一种控制系统与网络调度的集成仿真平台，并举例说明了策略的有效性．

| Abstract: | Networked control system(NCS) is a kind of real-time system with delay constraint.According to this characteristic,a model of NCS with temporal distance constraint is presented.Then,a scheme of bandwidth schedule in accordance with temporal distance constraint is proposed.Moreover,the scheme can cooperate with current networked control algorithms more effectively,guarantee both quality of control(QoC) performance and quality of network service(QoS),and optimize overall performance of NCS.According to tempor... |
