摘　　要：为预测卫星热控制系统温度、提高该系统故障诊断准确率 ,采用了基于模型的分析研究方法 ,并将Newton Щаманский方法应用于模型的求解中 ,提高了运算效率。通过建模和求解 ,获得了各节点在正常和各故障模式下的温度 ,给出了一种有效的故障诊断方法。Model-based analysis and research methods are adopted in this paper in order to forecasting the temperature and improve the accuracy of fault diagnosis on heat control system of satellite. Newton-Щаманский algorithm is applied in the solving of model. It enhances the efficiency of operation. The temperature at every point under normal and every kind of fault condition is obtained by making and solving the model. An efficient method about fault diagnosis is given.
