针对环境温度变化会影响加速度计输出从而导致测量精度变差的问题，研究了石英挠性加速度计组合温度控制系统的对象建模问题。工作过程中加速度计内部与外界存在温度梯度，实时地进行着热量交换，需要为加速度计组合设计精密的温度控制系统，确保加速度计工作在恒定的工作点从而提高导航精度。为了进行合理的温度控制系统回路设计，设计了多工作点加速度计升温实验，采用增广最小二乘法和近似支持向量回归对被控对象模型进行了辨识，辨识结果表明了方法的有效性。

To solve the problem that the precision of an accelerometer is influenced by the environment tem-perature,the controlled object modeling in the accelerometer unit temperature control system is researched. There is heat exchange between the inside of the accelerometer and the environment.In order to improve navi-gation accuracy,a precise temperature control system is designed to offer a steady temperature environment for the accelerometer.In order to design the logical closed-loop,the experiments of temperature rising with multi-operating points are conducted.The controlled object model is identified with recursive extended least squares and proximal support vector regression respectively.The experiment results demonstrate that the identified model is effective.
