| 摘 要： | 针对电站锅炉具有大惯性、大纯滞后、强干扰等特点，采用最小二乘和相关系数辨识相结合的方法建立系统数学模型；构造带前馈的串级控制器调节主蒸汽温度，控制器外环采用阶梯式广义预测控制，内环为PID（proportional—integral—derivative）控制；设计并使用了智能监督级，保证了先进控制的投用率．实际运行情况表明，该先进控制系统具有良好的控制品质．

| Abstract: | Boilers in power stations have the characteristics of large time constant,large pure time delay and strong disturbances.A model was proposed based on least squares method(LSM) and correlation coefficient identification approach,and a cascade controller was constructed with feedforward for main-steam temperature.Stair-like generalized predictive control was used in the outer-loop of the controller and PID control was used in the inner-loop.The supervisory shell for the controller was designed and used to increase its running-time.Application shows good quality of the advanced control system. |
