Overview of the development and key technologies of actuator for spacecraft ultra-quiet platform

The improvement of the sensibility and other related performance indicators of satellite-borne payloads calls for higher precision and stability of the spacecraft control system, and the spacecraft ultra-quiet platform with vibration isolation/depression and precise pointing functions has widespread attention. As the key executive component to realize the functions of the ultra-quiet platform, the actuator plays a decisive role for the task reliability and the lifetime of the platform. In this paper, the actuators of ultra-quiet platform are classified, and discussed according to their performance characteristics, the task background, and the technical development. In addition, the key technologies with respect to the high-efficiency voice coil motor, the long-life flexible element, and the ground test verification are reviewed. Finally, in view of the application requirements of high-precision spaceborne optical payloads in the future, some suggestions are made on the research projects worth to be further carried out in the field of the ultra-quiet platform actuator.
