【 摘 要 】

Gyrowheel is an innovative rate sensing and momentum management instrument. It could measure two-axes external angular rates and provide three-axes control torques at the same time. In order to improve the rate sensing performance, calibration tests are necessary to identify error terms and acquire compensation equations. However, there are too many possible error terms which make the calibration tests too complex to carry out. Considering that some of the error terms might be neglected without decreasing the compensation accuracy, proper test procedure to identify and neglect insignificant error terms is of great help to simplifying calibration tests and compensation equations. In this paper, a method to figure out and exclude insignificant error terms based on variance analysis is proposed. Test result shows that this method can simplified the form of the compensation equations without decreasing the compensation accuracy.
