| 摘 要： | 以完善推力器配置的性能分析为目的,从推力器配置对误差的鲁棒性以及燃耗这两个角度出发,提出了两项新的性能指标--配置阵的最小奇异值和平均燃耗.首先,由矩阵相关理论引入了配置阵的最小奇异值,并通过算例验证了它反映配置阵抗干扰能力的有效性;然后分析了控制指令的空间分布与配置推力矢量的空间分布之间的关系,通过仿真算例验证了它在反映不同配置的燃耗差异上的有效性.

| Abstract: | In this paper,two new performance indices are proposed for the performance analysis of the spacecraft thruster configuration.One is the minimum singular value of thruster configuration matrix.It can reflect the maximum size of the error matrix that a thruster configuration can endure while being feasible.The other is the average fuel consumption,i.e.the fuel consumption level of different thruster configurations.And then the analysis of the relation between the space distribution of control commands and the... |
