摘　　要：设计了基于微型旋转步进电机的陀螺灵敏部精密定位测量控制的结构,采用最优化升降速原则,实时精确定位,实现步进电机的稳态运行控制,并实现陀螺灵敏部下放时精确的位置和速度控制,时间短,效率高,克服了人工下放、托起陀螺房带来的耗时和不稳定性。实验结果表明:应用步进电机自动精确定位可以控制陀螺灵敏部摆幅为53′～139′,陀螺仪实现精密的寻北特性,寻北重复性定位精度达到8″。A gyro-house automatic and precise rising-lowering orientation measurement structure based on microrotation stepper motor is designed, which applies optimized acceleration ＆ deceleration principal and controls well. This control method is effective and has many advantages rather than traditional manual operation. The experience result shows that stepper motor plan rising-lowering gyro can control its valid pendular range 53＇- 139＇ and make the gyro theodolite represent fine norriS-seeking feature with repetition precision of 8＂.
