A digital control system for micro-comb gyroscope

Vibratory gyroscope exploit a coriolis force coupling between two degree of freedom internal to the sensor for detection of the sensor´s angular rotation rate. The peripheral circuit is the key part to realize the function of the gyro system. The peripheral circuit traditionally adopts pure analog circuit. However, the analog circuit has some inherent shortcomings. These limit the accuracy of the gyro. In this paper, a digital control system for micro-comb is introduced. According to testing the gyro performance is much improved by means of the digital control system.
