Embodiment Construction
[0029] The constant frequency driving method of the tunable micromechanical gyroscope is that the constant frequency driving signal has a constant frequency relative to the reference frequency source, and the phase difference signal between the constant frequency driving signal and the driving mode output signal is obtained through phase difference detection, and the phase difference signal is used to The feedback control obtains the tuning signal, applies the tuning signal to the tuning structure of the tunable micro-mechanical gyro, adjusts the resonant frequency of the driving mode of the tunable micro-mechanical gyroscope, and locks the resonant frequency of the driving mode to the frequency of the constant-frequency driving signal .
[0030] Such as figure 1 As shown, the specific steps of the constant frequency driving method of the tunable micromachined gyroscope are as follows:
[0031] 1) The AC drive signal generation module generates the AC drive signal according t...
