In order to fulfill the attitude control mission of micro flight vehicle delivered from a certain kind of ballistic missile , a fast attitude maneuver control approach based on the GPM ( Gauss pseudospectral method) was proposed.Firstly, the accurate attitude control model was established and the coupling torque term of the reaction wheels was taken into account.Secondly, the GPM was adopted to obtain the optimal attitude trajectories.Moreover, a quasi-sliding mode controller was designed to track the optimal trajectories.Numerical simulation results demonstrate the optimality of the attitude maneuver trajectories obtained by using the GPM , the good performances of the quasi-sliding mode controller in tracking the optimal trajectories, and the good effect in rejecting the external disturbance torque.%针对某弹道导弹释放的微小型飞行器的姿态控制任务需求,提出一种基于Gauss伪谱法的姿态快速机动控制方法.建立精确的姿态控制模型,并考虑反作用飞轮的耦合力矩项;采用Gauss伪谱法获取最优姿态轨迹,设计准滑模跟踪控制器以跟踪该最优轨迹.数字仿真结果表明,Gauss伪谱法计算得到的轨迹是最优的,准滑模跟踪控制器能实现对最优轨迹的良好跟踪,且对干扰力矩有较好的抑制作用.
