Abstract
The damping asymmetry of cylindrical resonators is one of the major sources which result in the gyroscope's drift. In this paper, a new approach for compensating the damping asymmetry of cylindrical resonators is proposed. The damping asymmetry compensation model is established to analyze the additional damping's influences. Furthermore, piezoelectric electrodes' effects on the cylindrical resonator's damping characteristic are figured out through the finite element simulation. At last, these theoretical analysis and simulation results are utilized to compensate the damping asymmetry of cylindrical resonators, which is also verified by experiments.
