摘　　要：基于半球谐振陀螺的结构特点及制造工艺技术限制等因素,研究了半球谐振陀螺的漂移机理。文中重点介绍了正交漂移及其控制,推导出正交漂移分量的数学模型。针对正交漂移产生的漂移速率和漂移角,给出了补偿和控制漂移的正交控制法。Based on limitation of hemispherical resonant gyro（HRG） structural characteristics and manufacturing technology,the basic drift mechanisms of HRG was studied. The quadrature drift and control were specially introduced and quadrature drift components equation was deduced. By analyzing drift velocity arid drift angle of quadrature drift, the method of quadrature control for compensating and controlling the quadrature drift was presented , it is very important for drift control of HRG.
