针对某些航天任务在小卫星机动过程中需要保持编队构型,提出了利用虚拟结构解决三星编队机动控制问题。建立了虚拟结构坐标系,在机动过程中,三颗卫星视为一个虚拟刚体,保持编队构型。设计了虚拟结构的动力学和运动学控制器。动力学控制器包含编队队形反馈,实现对编队速度的控制。针对外加干扰,设计了姿态变结构控制器,利用李雅普诺夫方法证明了系统的稳定性。对三星编队机动进行仿真,实现了编队构型的保持,验证了方法的有效性。
In order to maintain formation formation for some satellites in the process of small satellites maneuver, the virtual structure is proposed to solve the problem of maneuvering control of Samsung formation. The virtual structure coordinate system was established. During the maneuvering process, the three satellites were regarded as a virtual rigid body to maintain formation configuration. A virtual structural dynamics and kinematic controller is designed. Kinetic controller includes formation formation feedback, to control the formation speed. Aiming at the external disturbance, the attitude variable structure controller is designed and the system stability is proved by Lyapunov method. The simulation of the Samsung formation maneuver achieved formation formation maintenance and verified the effectiveness of the method.
