| 摘 要： | 在电厂安全稳定运行中,主汽温度是重要的参数之一。汽温过高或过低,都将给安全生产带来不利影响。针对火电厂主汽温对象大迟延,时变性的特点,将传统的PID控制器与模糊控制器相结合,构成了一种Fuzzy-PI复合主汽温控制系统,从而充分利用了模糊控制的动态特性好和PID调节能消除静差的特性。仿真结果表明,Fuzzy-PI复合主汽温控制器在控制品质上优于常规PID控制系统。

| Abstract: | In safe and stable operation of power plant,main steam temperature is one of important parameters.If the steam is too high or too low,it will bring on dangerous factors.In order to overcome the large delay and time-varying of the main-steam temperature object in fossil-fired power station,a composite main stream temperature control system which combines a fuzzy controller and PID controller.It fully use both the good dynamic characteristics of fuzzy control and eliminating static deviation of PID control.Th... |
