Controller Design of Deployment Process for Large Deployable Reflectors

Abstract

Large deployable reflectors are the key technical equipment to meet the needs of geostationary mobile communication in high rail and earth observation. After being sent to the working track by the spacecraft, the space antenna is driven by a reliable and stable controller to provide a frame for forming a high-precision metal reflecting surface. This paper aims to study the optimal deployment process control strategy and method based on the deployable trajectory for a large deployable antenna. In this paper, the Backstepping controller and fuzzy PID controller are designed respectively based on the model and non-model perspectives. The feasibility of the controller is verified by simulation, and the advantages and applications of the controller are illustrated by comparison. The article lays a good foundation for the technical improvement of the antenna system.
