基于加速度计的模糊自适应温度控制方法研究

Research on the Fuzzy Self-adapting Temperature Control Method of Accelerometer

在惯性导航系统(INS)工作过程中.加速度计输出的稳定性与温度有很大的关系,温度的稳定性直接影响着惯性导航系统能否快速启动并稳定工作。因此,研究精度高、快速性好的温度控制系统尤为重要。文中提出一种基于 DSP 的两级变结构温度控制方法。实验证明,该系统可以达到快速启动、输出稳定并能较好适应工作环境变化等要求。

In an INS,the stability of the output of the accelerometer is affinitive with the temperature,and the tempera- ture stability directly determines whether INS can work immediately and stably or not.So it is important to research on the temperature control system with high precision and good speediness.The paper puts forward a 2-level structure-Al- terable temperature control method based on DSP.The experimental results show that the controlling projection makes the system be sufficient for the demands of starting fleetly,outputting stably and adapting the environment preferably.
