摘要： An embodiment of the present invention relates to a combined accelerometer and gyroscope system. The combined accelerometer and gyroscope system includes a combined accelerometer and gyroscope for maintaining vibration of a mass body at a constant amplitude using an applied drive voltage, and detecting vibration signals in directions of an acceleration axis and an angular velocity axis. An acceleration axis vibration signal obtainment unit obtains the vibration signal in the direction of the acceleration axis. An amplitude maintenance control unit outputs an acceleration axis vibration maintenance control signal using the vibration signal. An acceleration axis driving input unit receives a voltage signal from the amplitude maintenance control unit and applies the voltage signal to the combined accelerometer and gyroscope. An angular velocity axis vibration signal obtainment unit obtains the vibration signal in the direction of the angular velocity axis. A force balance control unit outputs an angular velocity axis vibration maintenance control signal using the vibration signal received from the angular velocity axis vibration signal obtainment unit. An angular velocity axis driving input unit receives a voltage signal received from the force balance control unit and applies the voltage signal to the combined accelerometer and gyroscope.
