Error Compensation Technology of Semi-Strapdown MEMS Inertial Measurement System

Abstract:

Semi-strapdown inertial measurement method provides a new solution for the high-precision measurement on flight attitude of high-spinning ammunition, while the specific set of components in the semi-strapdown application will cause a series of errors. This paper mainly analyzes the generation mechanism of motor speed fluctuation error and the misalignment error in coupling axis. Then the instantaneous motor speed measurement method based on the high-precision gyroscope is designed and the misalign model of coupling axis is set up, MEMS inertial measurement area centripetal force equation under the condition of high speed is worked out, and accuracy error parameters affecting the measurement are obtained. Finally, the paper provides corresponding error compensation method and comparative tests are conducted. The results show that the compensated system improves the accuracy of attitude angle calculating and the error has been effectively suppressed.
