电站锅炉过热蒸汽温度是典型的分布参数对象,用传统的PID方法难以进行有效的控制.介绍运用Fuzzy-PI复合控制系统对100MW燃煤单元机组的过热汽温的控制进行了仿真研究,给出了模糊控制方法与传统方法的结果比较,说明模糊控制对这类对象的控制效果良好.
The superheated steam temperature of power plant boiler is a typical distributed parameter object, which is difficult to be effectively controlled by the traditional PID method.A fuzzy-PI composite control system is introduced to simulate the control of superheated steam temperature of 100MW coal-fired unit. The fuzzy control method compared with the traditional method shows that the fuzzy control has a good effect on the control of this kind of object.
