Abstract: In order to research the dynamic performance of a novel superfluid gyroscope, the factors which have effect on the detectable angular acceleration of gyroscope are analyzed. Based on the mathematic model of Josephson frequency for thermal driving, the detectable angular acceleration of gyroscope is simulated. The results show that, according to common parameters, the maximal value of detectable angular acceleration is about 0.32 rad/s2, so the dynamic performance of superfluid gyroscope is small. The gyroscope can be used for the field which requires the higher detection accuracy and slow change of angular velocity.

Key words: control science and technology, superfluid gyroscope, matter wave, Josephson frequency, dynamic performance, angular acceleration
