Abstract:This thesis has discussed the development and application of the digital pulse control system of crystal flexible accelerometer . It puts forward a method to reduce the fatigue strength of the pendulum plate of the crystal flexible accelerometer as low as possible by controlling the vibration amplitude of the pendulum plate of crystal flexible accelerometer through raising the system sample frequency . A digital pulse control model of crystal flexible accelerometer is designed under the direction of this thought . After simulating the control model it proves that the scheme is reasonable and feasibility . Thereby a crystal flexible accelerometer dual pulse width control circuit which outputs digital pulse signal directly is designed and developed . This control scheme has been applied in all new navigation equipments of the Tianjin Navigation Instruments Research Institute .
Keywords:analog control  digital pulse control  dual pulse width control
