Abstract: Regarding the shutter of space imager as the research background, the advantages and disadvantages of different types of shutters are introduced. The rotarydisc shutter is selected as the research object. Starting from the mode of exposure, the control strategy of shutter is investigated. The reason for selecting PMSM motor is analyzed, and a controller based on Digital Signal Processor (DSP) is designed. Furthermore, the maximum error of exposure time is less than 3.0%, which meets the performance requirements of telescope imager.

Key words: telescope, shutter, rotarydisc shutter
