摘　　要：所描述的泵浦光源温控系统,以飞思卡尔的MC9S12系列MCU芯片作为开发平台,基于成熟的PID控制算法,大胆引入了闭环负反馈控制结构,它所输出的控制信号,不仅可以成功地驱动TEC电路,而且还可以使其在20s内将温度调控到目标值。在精度方面,达到了±0.1℃的工业级精度,完全满足设计指标的要求。This temperature control is designed on MC9sl2 family chip,and the negative feedback loop was adopted for pump laser temperature controlling. The thermoelectric cooler （TEC）was driven by control signal, which was generated by MCU using proportional-integral-derivative （PID） controler algorithm. Diode pump laser temperature can reach the target value within 20 seconds, the working temperature stability was up to ±0.1 ℃.It meet the current requirements for generality pump source temperature indicators.
