多航天器系统分布式姿态协同预设性能控制
Distributed Attitude Cooperative Prescribed Performance Control for Multi-Spacecraft Systems
摘要
Abstract
Multi-spacecraft formation systems have received widespread attention due to their high flexibility and re-liability in executing space flight missions. This paper addresses the attitude coordination control problem of space-craft formation systems and proposes a distributed attitude coordination prescribed performance control method with fixed-time convergence. Firstly,the relative attitude dynamics model of spacecraft is constructed based on modified Rodrigues parameters,and the fixed-time convergence preset performance function envelope is adopted to quantita-tively describe the transient performance of the attitude error equation. Secondly,within the framework of preset performance control,a multi-spacecraft attitude coordination controller is designed,and the stability of the controller is demonstrated. Finally,the feasibility and effectiveness of the proposed method are verified through the simulation of two sets of multi-spacecraft attitude coordination stability and tracking control examples.关键词
