【摘要】 针对工业锅炉控制系统的特点,采用将常规PID控制与模糊控制相结合的控制策略,在常规PID调节器的基础上,采用模糊推理思想,根据不同的E、EC对PID参数Kp、Kl、Kd进行自校正。对锅炉汽包液位的控制表明这种模糊PID控制器可明显提高系统的性能。更多还原

【Abstract】 A control method based on combination ot fuzzy control and PID control is presented for characteristics of industrial boilers control system. The new kind of controller based on traditional PID controller employs fuzzy reasoning to accomplish PID parameters self-adjusting. Actual application for control of water level in steam drum presents that the fuzzy PID controller can improve the performance of system obvisouly.更多还原
