The invention discloses a silicon micro-resonant accelerometer temperature compensation algorithm based on structure compensation parameter adjustment. The capacitance voltage gain coefficient of a silicon micro-resonant accelerometer interface circuit is derived by a formula and is converted to a conversion coefficient of amplitude to output voltage of the silicon micro-resonant accelerometer, and the sensitivity of the capacitance voltage gain coefficient to temperature is given; an automatic gain control circuit stabilizes the amplitude of a resonant beam of the silicon micro-resonant accelerometer to the amplitude driven under given reference voltage, and when the capacitance voltage gain coefficient of the silicon micro-resonant accelerometer interface circuit changes along with the temperature and the temperature changes, a peripheral control circuit executes influences on the resonant frequency, and the sensitivity of the resonant frequency and the temperature is obtained; and through proper setting of temperature compensation structure parameters of the resonant structure, the target of suppressing drift of the frequency along with the temperature is achieved. No additionalsensor is needed for temperature compensation, the cost is low, no other influence quantity is introduced, and the compensation method is accurate and reliable.
