摘要：
Heat control subsystem is an important part of satellite for controlling the heat exchange between satellite and external environment and monitoring instrument temperature within the satellite. A model-based research method was adopted to forecast the temperature and improve the accuracy of fault diagnosis for satellite heat control subsystem. A mathematical model was established. It enhances the efficiency of calculation. The temperature at every point under normal and every kind of fault conditions can be obtained by solving the model. An efficient fault diagnosis method in terms of temperature monitoring was proposed.
