两种异步情形的网络控制系统的分析与建模

Analysis and Modeling of Two Kinds of Asynchronous Networked Control Systems

对具有时延、传感器和控制器为时钟驱动、执行器事件驱动方式下,传感器与控制器采样周期成整数倍和采样周期相同但存在时变偏差两种异步情形的网络控制系统的运行特性进行了分析,建立了相应的闭环数学模型.最后通过实例显示了该模型的合理性.

This paper focused on the analysis and modeling of asynchronous networked control systems. The characters of asynchronous networked control systems with different clock cycles in the presence of short time delays, and clock drift in the presence of limitary long-time delays have been analyzed. The time-droved and eventdroved models were compared. The discrete state-space models were formed. An example was analyzed, which proved the modeling was reasonable.
