摘　　要：为了在保证姿控和储能功能条件下设计出变速控制力矩陀螺(VSCMG)簇参数,在已有动量包络分析的基础之上,给出了考虑飞轮调速范围存在上限和下限约束条件下的动量包络空间和储能特性分析,提出了VSCMG簇的飞轮参数和构型倾侧角的优化设计方法.将VSCMG簇的参数优化设计问题描述为非线性、多约束、强耦合的单目标静态优化问题,采用序列二次规划算法求解优化问题,获得优化的单元参数,并计算出动量包络面,验证了所提出优化方法的有效性.Based on the existing results of the momentum envelop for the variable speed control moment gyroscope（VSCMG） cluster, in order to design parameters for the multifunction of attitude control and energy storage, the specificity analysis of the momentum envelop and energy storage under the condition of upper speed limit and lower speed limit of flywheel is firstly proposed. The optimal method of flywheel parameters and skew angle of pyramid configuration is cast as the nonlinear, multi-constrains, and strong coupling single objection optimal problem. The sequential quadratic program method is applied to solve the problem of optimal parameters. Finally, the momentum envelop, based on optimal parameters is calculated, and the results show the effectiveness of the proposed method.
