摘要: 针对具有随机时延的一类网络控制系统(NCS),文章设计了一种基于时延补偿和广义预测控制(GPC)算法的控制器。该控制器根据数据包的时间戳计算传感器-控制器时延,通过时延补偿得到被控对象当前的状态和输出,采用GPC算法计算控制量。仿真结果证实了该控制器的有效性。 更多还原Abstract: Aiming at a kind of networked control system(NCS) which contains random time delay,the paper designed a controller based on time delay compensation and generalized predictive control(GPC) algorithm. The controller calculated time delay of sensor-to-controller by analyzing time stamp of data packet, then it obtained the current state and output by time delay compensation and used GPC algorithm to calculated control signal. Simulation result proved effectiveness of the controller.
