Spacecraft Large Angle Maneuver Control Based on Inverse Dynamic

提出了一种基于逆动态理论的轮控空间飞行器大角度机动控制方法。用逆动态控制对系统作非线性解耦,基于变结构控制的鲁棒性设计控制器,给出了控制回路方案。仿真结果表明:该控制法在有外界干扰和系统参数不确定条件下有较快的收敛性和一定的鲁棒性。

The method of spacecraft large angle maneuver control with flywheel based on inverse dynamic theory was put forward in this paper. The system was nonlinearly decoupled using the inverse dynamic control. The controller was designed based on the robustness of variable structure control. The design of the control loop was given out. The simulation results showed that the control method had fast convergence and robustness, which was under conditions of exterior disturbances and uncertainty of system parameters.
