一种网络控制系统时延补偿方法

A Kind of method to compensate the time delay of NCS

本文分析介绍了具有随机时延网络控制系统控制器设计及时延补偿方法,采用广义预测控制(GPC)算法设计控制器。针对输出时延通过对时间加上时间戳来估算时间延迟,并采用状态观测器进行时延补偿,而控制时延则采用队列机制,增加缓存器的方法来保证被控对象获得最优控制信号。通过仿真证实该方法的有效性。

This paper analyzed and introduced the controller designing and the time delay compensation method for the Network Control system with stochastic time-delay quality, using generalized predictive control algorithm to design controller.Aiming at the control delay, we use states observer to compensate the time delay by adding time stamp to calculate out the time delay.As to the output delay we use the queuing strategy method and adding the buffer to guarantee the plant can get the optimal control signal.The simulation result proved the effectiveness of this method.
