This paper describes a design solution of automatic calibration platform based on MEMS accelerometer. Starting from mathematical model, the algorithm of angle measurement is calculated and the control program of leveling is designed. Improved PID algorithm is used in motor control to deal with the problem of performance degradation caused by output mutation. The mechanism of speed regu- lation can decrease leveling time in high speed gear, and ensure accuracy in low speed gear. Results show that the system runs stably and can be used on normal leveling occasions.
