摘　　要：介绍了一种大功率半导体激光器的精密Fuzzy+PI温控系统的设计,利用半导体制冷器对大功率半导体激光器进行精密温控,控制精度高、振荡小;在常规模糊PID控制器的基础上,通过增加模糊控制规则,从而构成变积分系数的模糊PI控制器,通过在线调整积分系数,间接调整常规模糊控制器的模糊控制规则,以改善其性能。A precise Fuzzy ＋ P1 temperature controller system for high - power laser - diode is reviewed. In order to control the temperature of the laser - diode, a semiconductor cooler is applied . The controlling preci- sion is high, and the oscillation of laser- diode＇s temperature is very small. In this paper, on the basis of normal Fuzzy controller, by adding rule of Fuzzy control, the varied integral coefficient Fuzzy PI controller is obtained. To improve normal Fuzzy eontroller＇s function, integral coefficient on line is adjusted to moderate its fuzzy rule indirectly.
