卫星太阳帆膜的形状对于三轴稳定姿态控制系统中的角动量卸载至关重要，因为三维太阳帆可以接收来自任意方向的太阳辐射压力。本文采用角动量卸载策略对三维膜结构太阳帆进行了形状优化。对太阳辐射压力力矩进行了建模和仿真，以卸载角动量。利用该仿真系统，以卸载角动量率最大为目标，采用遗传算法和序列二次规划相结合的方法对三维太阳帆的形状进行了优化。优化后的太阳帆的卸载速度比传统的平面或金字塔形太阳帆有很大的提高。(C)2021年空间研委会。Elsevier B.V.出版，保留所有权利。
A shape of the satellite's solar sail membrane is essential for unloading angular momentum in the three-axis stabilized attitude control system because the three-dimensional solar sail can receive solar radiation pressure from arbitrary directions. In this paper, the objective is the shape optimization of a three-dimensional membrane-structured solar sail using the angular momentum unloading strategy. We modelled and simulated the solar radiation pressure torque, for unloading angular momentum. Using the simulation system, since the unloading angular momentum rate is maximized, the shape of the three-dimensional solar sail was optimized using a Genetic algorithm and Sequential Quadratic Programming. The unloading velocity in the optimized shaped solar sail was greatly improved with respect to a conventional flat or pyramid solar sail. (C) 2021 COSPAR. Published by Elsevier B.V.
