| 摘 要： | 针对微小卫星、钠卫星编队飞行时的姿态和轨道控制要求,提出星载微推力器的概念,而激光微推力器在众多的微推力器中以能产生10^-7N·s-10^-4N·s的最小冲量受到了国内外研究学者的关注。激光微推力器系统包括五个分系统,通过采用软件芯片DSP驱动步进电机的控制策略对控制分系统进行设计,实验结果表明可以取得较高的控制准确度。

| Abstract: | According to the attitude control and orbit control of micro-satellite and nano-satellite, the concept the planet carrying micro-thruster is advanced. In numerous micro-thrusters, the laser microthruster is especially attentioned by researchers in because of its mini impulse of 10-6N · s· 10^ -4N·s. The whole thruster system is composed by five subsystems. The control subsystem is designed by utilizing DSP to drive stepping motor and has good performance by the experiment validation. |
