摘　　要：针对网络控制系统(NCS)中存在的网络延迟和数据丢包问题,利用提升技术,将预测控制器和网络延迟补偿器相结合,提出了一种基于多速率采样系统的网络预测控制算法.仿真试验表明,该算法对网络延迟和数据丢包具有一定的补偿作用,不仅提高了网络资源利用率,且能保证闭环网络控制系统是渐近稳定的.A class of networked predictive control algorithm based on multi-rate sampled system is proposed by lifting technique for the problems of network delay and package dropout and combining predictive controller with compensator of network delay. The results of computer simulations demonstrate that the network delay is compensated, performance requirement for NCS is optimized, network efficiency is improved, and the stability of networked closed-loop is guaranteed.

关 键 词：网络预测控制 多速率采样系统 网络延迟补偿
