600MW火电机组主汽温控制的一种设计方法

A design method of 600MW unit main stream temperature control

以600MW火电机组为背景．针对电厂主汽温被控对象的大惯性,大滞后特点．基于内模控制理论．设计了一种FPID《模糊PID)控制系统,内回路采用比例控制:外回路采用模糊内模控制。仿真结果表明．设计的控制器具有良好的位置跟随特性。

Based 600MW Unit,Considering that main-steam temperature is a big -inertial and big-lagged object , a fuzzy PID control system is presented based on the Internal Model Control （IMC） principle. The inside loop is controlled by proportional controller and the outside is controlled by FIMC, The simulation results show that the designed system has good position tracking.
