摘要
将动态矩阵控制与双信号对象相结合，可以得到双信号动态矩阵控制。双信号动态矩阵控制包括四个环节：预测模型，滚动优化，反馈校正和导前信号校正。但由于采样周期与导前区不匹配，当发生导前区扰动时过渡过程仍不理想。进一步在双信号动态矩阵控制的基础上引入比例调节器，形成比例—双信号动态矩阵控制。仿真结果表明，用该方法设计的蒸汽温度控制系统在跟踪设定值和克服扰动等方面都具有良好的控制品质。
The double signals dynamic matrix control (DSDMC) is presented by combining dynamic matrix control (DMC) with the plants with double signals. DSDMC contains four factors: predictive model, moving optimization, feedback correction and leading signal correction. Because the sampling time is not a match for the leading segment, the dynamic process is not very ideal when the disturbance from the leading segment takes place. In order to improved this point, the proportional controller is added to form P DSDMC. The simulation shows that the steam temperature control system with P DSDMC is excellent.
