| 摘 要： | 针对网络控制系统中存在的数据丢包问题,使用一种带有常值补偿机制的广义预测控制(Generalized Predictive Control,GPC)算法设计船舶航向保持的网络预测控制器.首先,利用TrueTime工具箱仿真使用传统GPC算法设计的船舶航向保持的网络预测控制器.然后,考虑数据丢包对船舶航向保持的网络控制系统造成的影响,使用带有常值补偿机制的GPC算法设计一种新的船舶航向保持的网络预测控制器并进行仿真.仿真结果表明,在数据丢包情况下,采用新方法设计的控制器可以减少船舶航向调节时间,从而改善船舶航向保持的网络预测控制器的控制效果.

| Abstract: | In view of data packet dropout problems in networked control system, the Generalized Predictive Control (GPC) algorithm with constant value compensation mechanism is used to design a ship course keeping networked predictive controller. First, TrueTime toolbox is adopted to simulate the ship course keeping networked predictive controller designed by the traditional GPC algorithm. Then, considering the effect of data packet dropout on the ship course keeping networked control system, the GPC algorithm with constant value compensation mechanism is used to design a new ship course keeping networked predictive controller. Simulation results show that the new controller can reduce the regulating time of ship course and improve the control effect of the ship course keeping networked predictive controller. |
