Abstract: An electrostatic torque feedback approach is used to solve the underdamping problem of a novel rotational gyro. The electrostatic torque feedback structure is designed, modeled and validated by finite element analysis. By comparing the dynamic responses of the gyro to different feedback conditions, the approach is demonstrated to be able to significantly improve the dynamic characteristics of the gyro. As feedback voltage increases, the system can infinitely approach the critically damped state from the underdamped state. Due to the restriction of dielectric breakdown and the side effect of the feedback strength on the magnitude-frequency response, the feedback voltage should be about 100 V, where, the overshooting of the unit step is reduced from 87% to about 5% and the settling time is reduced from 1.3 s to about 0.1 s compared with the open-loop system.

Key words: technology of instrument and meter, dynamic characteristics, electrostatic torque, rotational gyroscope, step response
