针对近地轨道集群航天器电磁编队飞行的动力学和控制问题,提出了一种非线性反馈控制方法.基于电磁力模型和地磁场模型,分析了地磁场对近地轨道电磁编队的影响;建立了集群航天器电磁编队高精度相对轨道动力学模型;基于Lyapunov稳定性理论设计了一种非线性反馈控制律,利用该方法对两星电磁编队维持控制进行了仿真验证.仿真结果表明,地磁场引起的电磁干扰力可以忽略,但是电磁干扰力矩的影响必须考虑;近地轨道集群航天器电磁编队是可控的,所设计的控制方法是可行的.
Aiming at the dynamics and control of electromagnetic formation flying of the near-Earth orbit cluster spacecraft, a nonlinear feedback control method is proposed. Based on the electromagnetic force model and the geomagnetic model, the influence of the geomagnetic field on the electromagnetic formation of the near-Earth orbit A high-precision relative orbit dynamics model for the electromagnetic formation of a cluster spacecraft is established. Based on the Lyapunov stability theory, a nonlinear feedback control law is designed to simulate the two-star electromagnetic formation sustaining control. The simulation results show that the geomagnetic field The electromagnetic interference force caused by it can be neglected, but the influence of electromagnetic torque must be considered. The electromagnetic formation of LEO orbit spacecraft is controllable, and the control method is feasible.
