Abstract�� According to the basic theory of the thermo-electric cooler(TEC),the temperature dynamic characteristics of the optic-fiber light source module was analyzed, and mathematics model was established corresponds to its. In the actual experimental test to light source module, the TEC module was driven by multi-point frequency of working current, and dynamic data of light source core’s temperature was sampled with sensing component, and the dynamic data was calculated and fit with least-squares method, then the result was close to mathematics model, so the parameters of the mathematical model were determined. MAX1978 single-chip temperature controllers for Peltier thermoelectric cooler module was used, and the best proportional-integral-differential(PID)compensating network based on temperature dynamic characteristics mathematical model was designed, then the temperature control system of the optic-fiber light source was achieved, the result shows that TEC temperature control system can control the light source precisely and steadily.
Keywords�� optic-fiber light source   temperature control   thermo-electric cooler   proportional-integral-differential compensating network
