Abstract

Focusing on the problem of poor adaptability, low frequency positioning accuracy and low stability of micro quartz tuning fork gyroscopes, a multi-frequency excitation algorithm isproposed. Firstly, the influence of the frequency accuracy of the driving signal on the performance of the gyroscope is analyzed. Secondly, the frequency tracking algorithm is introduced. Then, the multi-frequency excitation algorithm is proposed to accurately locate the resonant frequency of the gyroscope. At last, the frequency scanning method and the combination method of frequency scanning and particle swarm optimization are experimented. The experimental results show that, by the combination method, the stability of frequency location is doubled, the position accuracy is improved, and the frequency deviation is less than 0.5Hz.
