Summarizes the characteristics of Inertial Measurement System used to lift＇s track test and the importance of its calibrating platform. The hardware structure, the control algorithm and the software flow of Inertial Measurement System＇s calibrating platform are introduced. A solution using Minimum Variance Self-tuning Control Algorithm is presented. Using CARMA to describe the system, Ex- tended Least Squares Estimation to estimate the system＇s parameters, and Minimum Variance Self-tuning Control to Control the system＇s input. Finally enhances the calibrating platform＇s accuracy enormously. The results show that calibrating platform＇s performance could meet the design＇s demand. Key words：
