摘要
网络系统中存在着延时、丢包等问题,在传统的控制系统中引入网络作为信号传输媒介后,会降低系统的控制性能,甚至造成系统的不稳定。传统的控制方法对于网络控制系统已经不再适用,因此采用预测控制的算法对网络系统的时延问题进行了深入研究。通过Matlab仿真,结果显示网络预测控制能够在不稳定时延的网络环境中保证良好的控制输出。针对网络时延的预测控制的数学实现方法进行了详细介绍,对广大工程应用能够起到积极的引导作用。
There are problems such as time delay, packet loss in network systems. When it is introduced in traditional control sys- tems as signal transmission medium, the control performance will be deduced. In this paper, a predictive control algorithm is used to study time delay in networked control system. Matlab simulation results show that the network predictive control can ensure good control output. This paper focuses on mathematical realization of predictive control method for in detail and it plays an active role in guiding the engineering applications.
