To predicate the equilibrium temperature and simulate the heat variation influence of satellite thermal balance test more easily and correctly, a double layer lumped parameter model of the satellite equipment temperature was set up.
为了解决卫星热平衡试验中涉及的温度预测与变工况仿真试验问题 ,建立起星载仪器温度变化的双层集总参数模型 ,这一动态特性模型采用简单的嵌套结构 ,模型参数可以方便地运用系统辨识算法从卫星热平衡试验数据中获取 ,应用这一模型可以对不同星载仪器的温度变化进行分别的预测与仿真计算 ,从而大大减少了温度预测与仿真工作的计算量 。
