摘要：
The structural asymmetry of the MEMS rate-integrating gyro (RIG) mode produces a threshold and an angle-dependent bias (ADB) that cause gyroscopes operating in this mode to stop working at input rates below the threshold and degrade the linearity of the output angle. This defect in the RIG output angle is actually caused by a precession angular-rate bias that results from both damping asymmetry (anisodamping) and stiffness asymmetry (anisostiffness). This paper describes a novel compensation method based on Fourier series fitting combined with ...
