Nonlinearity Reduction in Disk Resonator Gyroscopes Based on the Vibration Amplification Effect

IEEE Transactions on Industrial Electronics, 2020
This article reports a novel method to reduce the electrostatic and capacitive nonlinearities in a disk resonator gyroscope (DRG) and to further improve its ultimate oscillation amplitude for performances improvement. The DRG consists of multiple rings, in the working mode, the outer rings always have larger deformation than the inner rings, which is ...

Damping Tuning in the Disk Resonator Gyroscope Based on the Resistance Heat Dissipation

2019 IEEE SENSORS, 2019
This paper presents a damping tuning method for the resonator with parallel plate capacitors for driving, sensing and tuning. This damping tuning method bases on the resistance heat dissipation and is easy to realize. The damping tuning theories are derived firstly, in which we find that the damping tuning and stiffness tuning in the resonator with ...

Calibration and Compensation of The Misalignment Angle Errors For The Disk Resonator Gyroscopes

2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL), 2020
This paper reports a new method of calibration and compensation for the misalignment angle between the pickoff axis and the forcing directions of the disk resonator gyroscopes. With this error eliminated, the driving control loop will be free of the disturbance from the couple of the angular velocity.
