中文摘要：

针对卫星姿态控制过程中推力器数目和分布的选取问题,给出了星上常用的4种推力器安装布局,通过相平面控制,给出了各个稚力器的喷气时间,通过对不同布局下系统的控制精度、燃料消耗和可靠性等方面进行分析和比较,给出了推力器布局设计准则.该准则表明系统的可靠性和燃料消耗是推力器布局设计的主要参考依据.

英文摘要：

Aimed at the problem of choosing appropriate amount and suitable arrangement of thrusters for satellite attitude control, four different configurations of thrusters are summarized. Thruster burn time is given under phase-plane control, and the design criterion is proposed with comparing of control accuracy, fuel consumption and reliability under different configurations. This criterion shows that the reliability and fuel consumption are the primary reference in the design of thruster configuration.
