The controlling system of the DC brushless servo motor of the locked position circle

This paper is intended to introduce the position DC brushless servo motor system used in the camera system of small satellites. The controller is based on DSP, and adopts AD2S82 as its axis-angle converter. Having the characteristics of a concise structure and an advanced control strategy, the research model can run steadily at low speed and locate positions accurately, thus coming up to the practical standards of the satellite camera system.
