摘　　要：针对具有参数不确定性、外部扰动和预设性能需求的航天器编队约定时间姿轨耦合控制问题,本文基于预设性能控制方法提出了一种低复杂度的约定时间编队姿轨耦合协同控制器,使得航天器在设定时间内形成编队,且编队误差满足预设的各种性能指标.首先,通过结合有限时间稳定概念引入一种约定时间性能函数,其系统稳定时间可以由使用者任意设定;然后,把约定时间性能函数与预设性能控制方法结合起来,提出了不依赖航天器质量和转动惯量等信息的约定时间编队协同控制器,保证了编队状态量的收敛性能和收敛时间,并使用李雅普诺夫理论证明了其稳定性.最后,通过仿真验证了该控制方案的有效性.This paper addresses the problem of appointed-time attitude and orbit coupled control for distributed space-craft formation with parameter uncertainties,external disturbances and requirements of prescribed performance.A low complexity cooperative controller was proposed based on the prescribed performance control method,which realized the spacecraft formationflying within the set time and the formation errors met the preset performance indexes.Firstly,an appointed-time performance function that can arbitrarily set the stability time of the system is introduced by using the concept offinite time stability.Secondly,by combining the appointed-time performance function with the prescribed per-formance control method,a appointed-time cooperative controller is designed to ensure the transient performance and the steady performance andfinite-time stability of spacecraft formation control system.And the controller is independent of spacecraft mass and moment of inertia.Finally,the Lyapunov stability theorem is applied to prove the stability of the control system,and numerical simulation results show the effectiveness of the control law.
