摘　　要：介绍了一种电厂主管节能恒压供水系统模糊-PID控制系统.针对电厂主管节能恒压供水系统普遍存在的大滞后和惯性的特点,把模糊控制和PID控制结合起来构成具有自调整修正因子的Fuzzy-PID控制器,在应用中获得了满意的控制效果.硬件设计中,利用1台变频器和1台软启动器相互配合,通过PLC的协调控制,实现了水泵的启动、控制,保证了系统的可靠性,又减少了系统的投资.A kind of Fuzzy-PID control water-supplying system for constant pressure is introduced in this paper. For its serious lag and inertia, the fuzzy controller and PID controller are integrated into the self-adjust modify factor Fuzz- y-PID controller and get the satisfied effect. A transducer is used and the start and the control of the pumps by the con- trol of the PLC are realized, which makes the system more stable and reduces the cost of the main pipe energy-saving in power system.
