多星编队飞行的分散式耦合控制技术研究

摘要

Decentralized relative attitude dynamics and kinematics models of multi-satellite formation flight are established. The Backstepping method is used to design the coupled controller based on the nonlinear relative position dynamics and the decentralized relative attitude dynamics of multi-satellite formation flight. A selective control strategy is suggested to guarantee the control efficiency and the mission-failure safety of multi-satellite formation flight. Numerical simulations have demonstrated the effectiveness of the decentralized coupled controller.%以多星编队飞行为研究对象,建立了多星编队飞行的分散式相对姿态动力学和运动学模型,结合卫星编队飞行相对位置的非线性动力学模型,利用Backstepping方法设计多星编队飞行的分散式耦合控制器.采用了一种选择性控制策略,能够保证多星编队飞行的控制效率和抗故障能力.数值仿真结果表明了所设计的分散式耦合控制器的有效性.
