【摘要】 针对以太网在网络控制系统中传输时延的不确定性问题提出了一种基于模型预测控制算法的时延补偿控制方案。通过时延预估的方式获得反馈通道和前向通道的时延,再根据系统性能要求,利用动态矩阵控制算法对控制系统进行补偿设计,从而克服网络延时对控制系统造成的不利影响。在 Matlab 环境下进行了仿真实验,结果表明了该算法的有效性。更多还原

【Abstract】 Based on model predictive control,a compensation algorithm is presented for Ethernet control systems with uncertain transmission delay.The delay times of feedback are calculated through pre-estimate method.According to the request of system performance,the control system is compensated using control algorithm to overcome the bad effect caused by the network delay.The algorithm is simulated using MATLAB software and the simulation results show that the control strategy is effective and feasible.更多还原
