Abstract: In order to improve the temperature control effect of micro-spacecraft, an active temperature control system using thermoelectric cooler is presented. A dynamical model of spacecraft temperature change is built up, and the temperature control effect is simulated and analyzed. Simulation results show that the temperature change of spacecraft electronic equipment can be successfully controlled, and the dynamical models presented can be convenient used in thermoelectric cooler temperature control system’s simulation and optimization.
