基于改进自主避障算法的星群重构预设时间控制
Predefined-Time Control for Satellite Swarm Reconfiguration Based on Improved Autonomous Obstacle Avoidance Approach
摘要
Abstract
This paper focuses on the reconfiguration control method of the satellite swarm under the action of space environment force. The continuous finite-time convergent extended state observer (FTCESO)is designed to realize the estimation of the relative motion of the satellites and the uncertain perturbation in the space environment in finite time. A non-singular fast terminal sliding mode controller (NFTSMC)is designed to achieve fast stabilization of the system in a finite time. Based on FTCESO and NFTSMC,the predefined-time controller is developed for the recon-figuration process of the satellite swarm to drive the leader in the swarm from the initial configuration to the desired configuration. Meanwhile,based on the improved artificial potential field method,the autonomous obstacle avoid-ance and cooperative control approach between followers around each leader satellite is proj ected to ensure the geo-metrical reconfiguration and topology construction in a predefined time and maintain the stability of its own opera-tion,to meet the requirements of special space missions.关键词
