摘　　要：针对环境减灾二号A/B卫星的双轴机动及对日对月惯性目标定向需求,开展了基于四元数的双轴机动和对惯性目标定向控制研究。根据建立的挠性卫星姿态跟踪控制误差方程,给出比例、积分、微分(PID)控制律,双轴机动仍采用欧拉角形式进行控制,同时考虑多轴机动过程中偏流角的补偿算法;惯性目标定向采用四元数控制方式,可以实现对惯性目标定向,同时也可以实现绕某轴匀速扫过惯性目标。文章给出了几种姿态机动的仿真算例及在轨实现数据,结果表明:机动时间和姿态稳定度均满足卫星的多轴机动和对日对月定标要求。According to HJ-2A/B satellites’requirements for double-axis maneuver and orientation to inertial coordinate(including orientation to the Sun and the Moon),an attitude control method based on quaternion is studied.The error equation of flexible satellite attitude tracking control and the corresponding PID control law are established.Euler Angles are still used to control double-axis maneuver,and the compensation algorithm of Drift Angle in maneuver processing is considered.Quaternion control is used to orientate inertial coordinate,and both orientation direct to inertial coordinate and uniformly sweeping an inertial target around one axis could be achieved.Several simulation examples and attitude data in orbit of attitude maneuver are given,and the results show that maneuver time and pointing accuracy can meet the requirements for satellite double-axis maneuver and orientation to inertial coordinate.
