【 摘 要 】

Temperature drift is one of the main error sources of mems gyroscope. This paper introduces a temperature control system which uses the pid control algorithm that optimized by ant colony algorithm to realize the accurate control of temperature. This paper introduces the overall block diagram of the system, focusing on the temperature collecting and control module and the flow chart of software programming. And the experiment is carried out on the basis of the designed system, the experimental data is displayed in the upper computer software via wireless module and serial port, and the data is analyzed. The analysis results show that the designed system can achieve high precision temperature controlling.
