The invention discloses a micro-nano satellite formation multi-target attitude control method and system based on an array antenna. The method comprises the following steps: firstly, initializing a micro-nano satellite formation model; wherein the micro-nano satellite formation comprises a master spacecraft, a service spacecraft and any slave spacecraft which form a master-slave structure; then calculating a bidirectional LOS vector by using an MIMO communication technology and a CDMA technology; and finally, according to the bidirectional LOS vector and the angular velocity of the spacecraft, calculating control input, so that the control input reaches an expected relative attitude, and completing multi-target attitude control of the micro-nano satellite formation. The method reduces the dependence on a high-precision sensor, reduces the cost, improves the reliability and flexibility of the system, can achieve the precise attitude control of each satellite in the micro-nano satellite formation, and can be widely used in the technical field of micro-nano satellite formation attitude control.

    本发明公开了一种基于阵列天线的微纳卫星编队多目标姿态控制方法及系统,方法包括:首先初始化微纳卫星编队模型;其中所述微纳卫星编队包括一艘主航天器、一艘服务航天器、任意艘从航天器,形成主从式结构;然后利用MIMO通讯技术与CDMA技术计算双向LOS向量;最后根据所述双向LOS向量以及航天器角速度,计算控制输入,使得所述控制输入达到期望相对姿态,完成对所述微纳卫星编队的多目标姿态控制。本发明减少了对高精度传感器的依赖,降低了成本,同时也提高了系统的可靠性和灵活性,可以实现微纳卫星编队中各卫星的精确姿态控制,可广泛应用于微纳卫星编队姿态控制技术领域。
