摘　　要：陀螺加速度计的外环干扰力矩包括仪表外环轴的摩擦力矩和交叉轴加速度引起的交变力矩。本文分析了引起陀螺加速度计外环干扰力矩的主要原因,提出采用三轴台与陀螺加速度计构成闭环伺服系统分离陀螺加速度计外环干扰力矩试验方法,设计了自动增益补偿电路、增益匹配电路和稳定闭环投入电路,并成功地将三轴台伺服陀螺加速度计系统投入运行,完成了陀螺加速度计分离外环干扰力矩试验。为改进陀螺加速度计的工艺和补偿外环干扰力矩提供了试验依据。The outer gimbal disturbance torque of PIGA（pendulous integrating gyro accelerometer） includes the outer gimbal axis friction torque and the alternating torque caused by the intersecting acceleration.The main reasons of generating the outer gimbal disturbance torque of PIGA are analyzed,and a method of the outer gimbal disturbance torque of PIGA on three-axis test turntable with high-precision and a closed loop servo system involved by using three-axis turntable and PIGA is presented.The automatic gain and compensation circuit,gain matching circuit and stabilized closed loop delivery circuit are designed.The servo PIGA system of three-axis turntable is implemented successfully by accomplishing the test of separating outer gimbal disturbance torque on PIGA,which provides the environmental basis for improving PIGA technique and compensating outer gimbal disturbance torque.
