摘　　要：讨论了具有多个闭环控制回路的网络控制系统中网络信号传输周期的任务调度问题。对具有时间延迟的单调速率调度算法在网络控制系统中的可调度性进行了理论分析,给出了保持系统稳定运行的可调度性条件。在此基础上,对调度算法的计算结果进行多目标优化,得到保证网络信号传输误差率最小及延迟时间最少的传输周期。网络控制系统实例证明了调度算法的实用性及优化结果的正确性。The task scheduling problem on network signal transmission periods are discussed in networked control systems that have multi-closed control loops. The schedulability of delayed rate-monotonic algorithm in NCS is analyzed in theory. And the condition of scheduling keeping the system stability is given. Furthermore, we get the transmission periods guaranteeing the network signal transmission errors minimized and the delay-time reduced hy multi-objective optimizing the computing result of scheduling algorithm. The algorithm practicability and the result of optimizing validity are proved by example of networked control systems.
