Stability Analysis and Simulation Research of Flexible Gyrocompass

This paper solves angular velocity of absolute motion of gyroscopeaby. direction cosine matrix and establishes the motional equations of flexible gyrocompass. Analyses of error and computer simulation of gyrocompass motions are made, and the conditions of stability are discussed. Finally, in the case of that angular momentum H, tuned frequency q_o and designed latitude (?) are determined, influences of transfer coefficient K_y of azimuth control loop and transfer coefficient K_z of level control loop on system stability have been analysed.
