摘　　要：利用基于最小均方(LMS)算法的自适应滤波器对过热汽温对象进行模型辨识,得到脉冲响应模型,再结合模型算法控制(MAC)理论构成过热汽温的MAC-P串级预测控制系统。该方法实施简单,仿真结果表明该控制方案具有较好的控制品质和鲁棒性。Based on the least mean square（LMS） adaptive filter algorithm,the model of the superheated steam temperature object was identified,and the impulse response model was obtained.Combined with the model algorithmic control（MAC） theory,the MAC-P cascade predictive control system of the superheated steam temperature was then composed.The method could be implemented easily.Simulation results showed that the control strategy had relatively good control quanlity and robustness.
