The invention discloses a combined type double-degree-of-freedom sun alignment system which comprises an A-axis sun alignment subsystem, a B-axis sun alignment subsystem and a truss assembly. The A-axis sun-oriented subsystem and the B-axis sun-oriented subsystem are orthogonally mounted on a spacecraft cabin through a truss assembly; the A-axis sun-oriented subsystem is used for realizing A-axis rotation control of the solar cell wing; and the B-axis sun orientation subsystem is used for realizing B-axis rotation control of the solar cell wing. According to the combined type double-degree-of-freedom sun-oriented system, double-degree-of-freedom sun-oriented orientation is achieved through the A-axis sun-oriented orientation subsystem and the B-axis sun-oriented orientation subsystem, so that it is guaranteed that under the conditions of different flight orbits and flight attitudes of a spacecraft, the sun incident angle reaches the optimal state, and the power generation capacity of solar cell wings reaches the maximum capacity; stable power output is provided for the spacecraft; and meanwhile, sun-oriented driving torque and stalling locking torque are provided for the large-inertia flexible solar cell wing, and high bearing performance is achieved.

    本发明公开了一种组合式双自由度对日系统,包括:A轴对日定向子系统、B轴对日定向子系统和桁架组件;A轴对日定向子系统和B轴对日定向子系统通过桁架组件正交安装在航天器舱体上;A轴对日定向子系统,用于实现太阳电池翼A轴向转动控制;B轴对日定向子系统,用于实现太阳电池翼B轴向转动控制。本发明所述组合式双自由度对日系统,通过A轴对日定向子系统和B轴对日定向子系统实现双自由度对日定向,以保证航天器在不同飞行轨道、飞行姿态条件下,太阳入射角均达到最优状态,太阳电池翼发电量达到最大能力,为航天器提供稳定的功率输出;同时,为大惯量的柔性太阳电池翼提供对日定向驱动力矩和停转锁定力矩,具备高承载性能。
