Study on the Temperature Control System for Azimuth Holding in Land Vehicle Navigator

针对方位保持部件温控系统 ,提出了一种分时分段 PID控制与级间控制相结合的三级温控方案 ,以及用遗传算法进行参数整定的方法。同时 ,介绍了温控系统的软、硬件实现 ,并给出了试验结果。

In this paper,a three-level temperature control plan combining grade-control with PID control in terms of the range of temperature and time for the azimuth holding organ is proposed,and the parameters is optimized based on genetic algorithm.the software and hardware design of the temperature control system is described.At the end the result of trials is presented.
