摘　　要：基于模糊控制原理,采用模糊控制与PID控制相结合的模糊控制方法,完成了一种针对半导体激光器温度控制的算法设计。该模糊PID控制算法,能够自适应调节PID的比例、积分和微分系数,从而使半导体制冷器的温度保持恒定。Simulink仿真结果表明,采用该模糊PID控制算法后系统的超调量减少40%,缩短了调节时间,控制效果优于常规PID控制系统。Based on theory of fuzzy control, a combination method of fuzzy control and PID control is used, which is known as fuzzy PID control. A semiconductor laser temperature control system design is completed. It can adaptively adjust PID proportional, integral and differential coefficient to keep the semiconductor cooler＇ s temperature con- stant. The simulation results of Simulink show that, after using the fuzzy PID control algorithm the overshoot of the sys- tem is reduced by 40%, the adjustment time is shorten and the control effect is better than conventional PID control system.
