%X Two different application modes of flexible gyroscopes, i.e. open loop and close loop, are presented. The stability of a system in both application modes is analyzed in terms of torque rigidity. In theory, the torque rigidity of a system is limited by the bandwidth of the gyroscope when it operates in the close loop mode. In the open loop mode, the torque rigidity of the system is not limited by the bandwidth of the gyroscope and can be increased greatly. The simulation and test result shows that the open loop mode is more effective than the close loop mode for a gyroscope. It can improve the torque rigidity and stability of the system. This result validates the correctness of the theoretical analysis.
