The invention discloses a design method of a novel CMG control law with feedforward compensation, which belongs to the field of spacecraft control. A spacecraft GNC module not only calculates the frame angular velocity instruction of each CMG in each control period, but also calculates the gyroscopic moment applied to each CMG frame axis due to the influence of the star angular velocity, and the two parts are simultaneously provided for a CMG single machine for determining the control law. Compared with the prior art, the method provided by the invention has the advantages that feedforward compensation is carried out on the CMG single machine by utilizing the information of the gyroscopic moment, so that the constraint on the star angular velocity is relaxed, and the problem of CMG stall occurring when the star angular velocity is relatively high is solved.

    一种带有前馈补偿的新型CMG操纵律设计方法,属于航天器控制领域。航天器GNC模块在每个控制周期内不仅计算各个CMG的框架角速度指令,而且计算由于星体角速度影响而施加在各个CMG框架轴的陀螺力矩,将这两部分同时提供给CMG单机,用于确定控制律。与现有技术相比,本发明给出的方法利用陀螺力矩的信息,对CMG单机进行前馈补偿,从而放宽对星体角速度的约束,解决星体角速度较大时出现的CMG失速问题。
