| 摘 要： | 在建立网络控制系统模型时,节点驱动方式的不同,对整个系统的实时性、稳定性以及鲁棒性等理论研究产生很大影响;通过分析网络节点在四种驱动方式下的动作时序和数学模型,用MATLAB/TrueTime仿真工具箱仿真测试了不同驱动方式在不同延时条件下所表现的特性:小时延情况下,事件驱动的网络控制系统性能优于时钟驱动的网络控制系统性能,而当网络负荷较重,尤其出现大时延时,采用时钟驱动的网络控制系统配合先进预估控制策略,将会得到较好的系统性能。

| Abstract: | It is important to select the node driven mode when build a system model of networked control system.Different driven mode can have different influence on the performance of the system,including the research of the theory of stability and robustness.This paper analyzes the action sequence and mathematical model of the network node driven by four kind of mode,simulate and test the characteristic performed in different network delay by MATLAB/TrueTime Toolbox.In case of short delay,event driven modes to the c... |
