The application provides a
silicon photon gyroscope stable control method and
silicon photon gyroscope under a rapid temperature changing condition, and the stable control method comprises the following steps: setting a
light source frequency control digital interval; controlling the
light source temperature to make the
light source center frequency enter a
resonance valley, and recording the valley entering temperature; collecting the CW and CCW
resonance signals output after the light source enters the
resonance cavity, and calculating the sum of the
clockwise and counterclockwise resonance frequency and the light source
center frequency deviation; and calculating the
feedback control light source current and temperature according to the light source frequency control digital interval where the sum of the
frequency deviation is located. Through the
adaptive control of the light source current and temperature, the light source
center frequency can quickly track the resonance frequency of the resonance cavity under the rapid temperature changing condition, the stable control of the
gyroscope is realized, and the gyroscope output accuracy is improved.
