摘要
网络控制系统是一种新兴的通过网络传输数据的实时反馈控制系统。基于线性时不变控制对象,在仅存在不大于一个采样周期的时延影响的情况下,建立了该网络控制系统的离散模型,并基于此模型进行稳定性分析,并得出了判断系统达到渐进稳定的方法,最后进行了仿真验证,仿真结果表明该方法正确有效。
Feedback control systems wherein the data is transmitted through a real-time network are called networked control systems.Based on the linear time-invariant object,the mathematic discrete model of networked control systems is set up when the network induced delay is not longer than a sampling period,then stability based on this mathematic discrete model is studied and a stability analysis method is obtained.In the end the simulation based on the method is studied.The simulation results show the method is effective.
