摘　　要：针对汽化冷却系统汽包水位控制常用的三冲量控制方法中采用PID作为控制器的一些不足,提出一种新的控制方法:用模糊控制完全替代PID算法,构建水位模糊控制器和假水位模糊控制器,并通过假水位判定,构成双控制器切换控制系统,对汽包水位进行控制,以期获得抗干扰能力强、鲁棒性好,控制精度高的优良调节品质。In the discourse,aiming at the shortage of PID controller used in 3-impluse control which is used for boiler level control of boil off cooling system,a new control way is bring forward that the PID algorithm is replaced by fuzzy control to set up water level fuzzy controller and false water fuzzy controller,and double controller switched to control water level by false water level judging.The result could be anticipated that the anti-interference should be powerful,the accuracy should be high,robustness should be good and the better control quality should be achieved.

关 键 词：水位模糊控制器 假水位模糊控制器
