Robust adaptive attitude trajectory tracking control method for aerospace craft

The invention relates to a robust adaptive attitude trajectory tracking control method for an aerospace craft. The method comprises the following steps: designing a redundant aerospace craft system; controller design: converting a gain matrix in the redundant aerospace craft system into a square matrix; the control input of the redundant aerospace craft system is constructed, and the tracking error between the actual trajectory and the expected trajectory of the redundant aerospace craft system is converged to zero through a controller. By means of the method, the aerospace craft system can track the target trajectory, and the tracking error is converged to zero. 本发明涉及一种航天飞行器的鲁棒自适应姿态轨迹跟踪控制方法，包括对冗余航天飞行器系统进行设计；控制器设计：将冗余航天飞行器系统中的增益矩阵转化为方阵；将冗余航天飞行器系统的控制输入进行构造，通过控制器使冗余航天飞行器系统的实际轨迹与期望轨迹之间的跟踪误差收敛到零。通过发明方法，航天飞行器系统能够实现对目标轨迹的跟踪，且跟踪误差收敛到零。
