| Abstract: | An orbit temperature control system with high precision and stability is designed, which is aimed to satisfy the temperature requirements of satellite-borne multi-channel shortwave infrared detectors. First of all, according to the demand of operating temperature, the precision requirement of the shortwave infrared detector is presented. Then, the circuit，which acquires temperature with high stability as well as control thermal with low noise, is designed. Meanwhile, the pulse width modulation signal, established by FPGA based on the switch control algorithm, is used to control current of the thermoelectric refrigerator. The requirement of high stability temperature control with limited resources has been realized. The final test results show that the precision of the control system can reach ±0.1°, and meets the accuracy stability requirement of operating temperature. |
