A Stabilisation Scheme of a Stepping Motor for a Fiber Optic Gyrocompass System

광파이버 자이로콤파스 시스템을 위한 스텝핑모터의 안정화

This paper describes a study of a stabilisation scheme of a stepping motor in the driving systems of the Fiber Optic Gyrocompass absolutely required a constant speed and a precise position control with fine step angle. The new stabilisation scheme combining microstepping control and frequency modulation is developed which enables the experimental machine to be capable of stable running to a stepping frequency in the range 5 times the open-loop stall frequency.
