Abstract Control algorithms for the active magnetic attitude control systems are covered in the survey. Three different situations in the magnetic system implementation are considered. First, angular velocity damping is covered. Second part is devoted to the combined operation of the active magnetic system with other actuators and with the help of some passive stabilization concepts. Magnetic control torque is restricted in its direction, as it cannot be implemented along the geomagnetic induction vector. This restriction may be lifted by enhancing the active magnetic attitude control with other actuators and concepts. This comes at the cost of restrictions on the available attitude modes of the satellites. Namely, passive gravity-gradient stabilization provides the nadir pointing; bias momentum satellites are restricted by the wheel axis pointing along the orbital normal; spin stabilized satellites acquire only one axis attitude. Finally, solely three-axis magnetic attitude control is considered. Different approaches to the control torque restriction problem are covered, with distinction between the local feedback laws and optimization methods. The survey does not cover passive magnetic control concepts and auxiliary role in the reaction wheels momentum unload. Comparison of the covered algorithms is provided to highlight the authors’ opinion on the algorithms modern implementation and further research directions.

小卫星主动磁姿态控制算法综述

摘要 本研究涵盖了主动磁姿态控制系统的控制算法。考虑了磁系统实现中的三种不同情况。首先，角速度阻尼被覆盖。第二部分致力于主动磁系统与其他致动器的组合操作，并借助一些被动稳定概念。磁控制转矩在其方向上受到限制，因为它不能沿地磁感应矢量实现。可以通过使用其他致动器和概念增强主动磁性姿态控制来解除这种限制。这是以限制卫星可用姿态模式为代价的。也就是说，被动重力梯度稳定提供了最低点指向；偏置动量卫星受到沿轨道法线指向的轮轴的限制；自旋稳定卫星只获得一个轴姿态。最后，仅考虑三轴磁姿态控制。涵盖了解决控制转矩限制问题的不同方法，区分了局部反馈规律和优化方法。该调查不包括被动磁控制概念和反作用轮动量卸载中的辅助作用。提供了所涵盖算法的比较，以突出作者对算法现代实现和进一步研究方向的看法。涵盖了解决控制转矩限制问题的不同方法，区分了局部反馈规律和优化方法。该调查不包括被动磁控制概念和反作用轮动量卸载中的辅助作用。提供了所涵盖算法的比较，以突出作者对算法现代实现和进一步研究方向的看法。涵盖了解决控制转矩限制问题的不同方法，区分了局部反馈规律和优化方法。该调查不包括被动磁控制概念和反作用轮动量卸载中的辅助作用。提供了所涵盖算法的比较，以突出作者对算法现代实现和进一步研究方向的看法。
