| 摘 要： | 针对网络控制系统(NCS)中的时延问题,在分析网络时延特性的基础上,对系统采用预测控制策略进行时延补偿,该策略用易于测量的网络往返时延代替不易单独测量的前向时延和后向时延,并用MATLAB/TrueTime仿真工具箱对实际系统进行了仿真实验研究.仿真结果表明该策略能保证网络控制系统的良好性能.

| Abstract: | Aiming at the problem of time delay in network control system (NCS),a predictive control method is presented to compensate the random delays.The method is based on the round trip time (RTT) delay which is easier to measure than for- ward delay and backward delay which are difficult to measure individually,and MATLAI3/TrueTime toolbox is obtained to simulate experiments for the actual system.The results of simulation show that excellent network performance is ensured by this strategy. |
