摘　　要：本文推导了静电陀螺仪转子动量矩的运动方程,根据此方程并应用向量场理论,将造成静电陀螺漂移的外部干扰力矩划分为守恒力矩和非守恒力矩两部分。按照进动规律,最终得到静电陀螺监控器中陀螺仪漂移误差模型的全量形式。In this paper, the kinetic equation of rotor angular momentum vector for electrostatic gyro(ESG) is derived. Based on the result and using vector field theory, the disturbing torque, which leads to the ESG drift, can be divided into two parts, i.e. conservational moment and non-conservational moment. According to the precession rule, the integrated drift error model of ESG in ESGM is given.
