Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] In the selection process of the thruster, the least thrust and the least control error caused by the thrust configuration should generally be considered. In order to reflect the proportional coefficient between the control error influenced by the relative geometric relationship of the thruster and the expected control quantity, the fuel consumption factor CDOP is defined as follows:
[0037] CDOP=tr[DD T ]
[0038] The smaller the fuel consumption factor CDOP, the smaller the control error caused by the thrust configuration. When the thruster layout is constant, as the number of engines participating in the allocation increases, the configuration fuel consumption factor CDOP also increases correspondingly, and the allocation error increases. Therefore, from the perspective of reducing the allocation error, the number of engines participating in the ...
