| 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. |
