Due to rotor mass imbalance, magnetic suspension control sensitive gyroscope (MSCSG) has synchronous vibration. In order to reduce the influence of the above unbalance vibration on the performance of MSCSG and the measurement accuracy of angular velocity, a method to suppress the imbalance vibration...
