| 摘 要： | 提出一种基于网络传输误差的控制系统调度方法，分析经典的静态和动态调度策略，给出通信网络的可调度性判据和网络调度下的控制性能稳定性约束。针对不可调度情况，使用网络监测得到网络传输误差，调整传感器的采样周期和在控制器进行数据包补偿的方法，并通过仿真实验验证该方法的有效性。

| Abstract: | This paper proposes a schedule method based on network-induced error is designed to solve collision of communication in network control systems. Traditional static and dynamic schedule policy is analyzed, criterion to satisfy network resource scheduling is given, some restrictions to get good stable performance is brought out. For under schedule, by monitoring network-induced error, to change sensor' sample periods and to remedy sample data in controller. Simulation validates the effectiveness of the proposed schedule method. |
