Based on the magnetic levitation gyroscope rotor torque feedback control model,the paper took into consideration of the force equation of magnetic rotor,sensitive torque and the disturbance torque under the uneven treatment,and made a simulation analysis of sampled data within the system stator and rotor.The results show that gyro stator has a good stability and is less vulnerable to the impact of interference torque.However the rotor is sensitive to disturbance torque,the sampling data can achieve real-time simulation of gyro north state.
