摘要 为了改善微型航天器的温度控制效果,介绍了一种应用热电制冷器的主动温度控制系统,建立了这种温度控制系统受控对象及辐射器温度变化的动态特性模型,并对受控对象内部热源功率发生变化时的温度控制效果进行了仿真分析。仿真结果表明:热电制冷器和PI控制器相结合可以简便有效地完成微型航天器内部电子设备的温度控制任务,动态特性模型为这种温度控制系统的优化设计提供了简便的数学模型。 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.
