This paper is experimental study of a cylinder shell resonator gyroscope actuated and sensed by piezoelectric material which has electromechanical conversion characteristics. Design a circuit that can drive the gyro vibration in (n=3) modal continuous. When the gyro start to rotate, the node of (n=3) modal has a displacement due to the Coriolis effect, design another circuit to control the gyro stably and measure the signal of control system. Finally, this paper get the relationship between the signal of control system and angular velocity, the result can be used in ±1 rpm~ ± 3 rpm.
