The invention relates to a relative motion control and angular momentum management method for an electromagnetic formation, and the method comprises the steps: building a six-degree-of-freedom relative dynamics model of the electromagnetic satellite formation, and determining a leader satellite and a follower satellite; selecting a leader satellite to install a reaction wheel, designing a magnetic moment for the satellite based on a frequency division multiplexing method, generating effective electromagnetic force and moment, and designing a direct current component for angular momentum unloading; designing a six-degree-of-freedom relative motion controller under the conditions that the electromagnetic formation system has external interference and the model is uncertain by adopting an active disturbance rejection control method; and designing an unloading law to unload the angular momentum of the reaction wheel of the leader satellite, and solving the direct current component of the magnetic moment of the leader satellite. According to the invention, relative position control and angular momentum management are decoupled by using the idea of frequency division multiplexing, so that angular momentum unloading and formation control are carried out in parallel.

    本发明涉及一种电磁编队的相对运动控制与角动量管理方法,包括:建立电磁卫星编队的6自由度相对动力学模型,确定领导者卫星和跟随者卫星;选择领导者卫星安装反作用轮,基于频分复用方法为卫星设计磁矩,产生有效电磁力和力矩,并设计用于角动量卸载的直流分量;采用自抗扰控制方法设计电磁编队系统存在外界干扰、模型不确定性情况下的6自由度相对运动的控制器;设计卸载律对领导者卫星的反作用轮的角动量进行卸载,并求解领导者卫星的磁矩的直流分量。本发明,利用频分复用的思想将相对位置控制和角动量管理解耦,实现了角动量卸载和编队控制并行进行。
