| 摘 要： | 针对多个推力器斜装且耦合强的复杂配置情况，首先基于矩阵范数理论提出一种适用于分析复杂推力器配置控制能力的性能指标——最小上界指令，给出其计算公式，并通过算例验证了该性能指标在评价配置控制能力的有效性；然后讨论推力矢量的幅值和几何分布对于该性能指标的影响；基于该性能指标，建立一个含参数配置阵的优化设计非线性规划模型，讨论了以增强配置控制能力为目标进行配置参数优化设计的方法．

| Abstract: | A new performance index for assessing the control capability of complex thruster configurations （non axis-symmetric configuration with coupling effects） is proposed,which is denominated as the least upper bound control command in this paper. Formula for calculating this index is deduced based on the matrix norm theory, and configuration factors affecting the index are discussed. This index is used as an objective function, and a non-linear programming model for the optimal thruster configuration design is established. Finally, a thruster configuration example is given to demonstrate its validity. |
