摘要
为解决多星发射上面级分离卫星后质量不对称性造成的姿态控制通道间的交连耦合,提出了非线性解耦控制和轨控发动机预摆控制两种控制方案,并对两种方案进行了数学仿真。通过仿真证明两种方案的正确性和鲁棒性,同时通过对仿真结果的分析得到了具有一定工程意义的结论。
In order to solving the coupling between attitude control channels caused by asymmetry of mass after the multi-satellite upper stage separating the subsatellites, two control methods including the nolinear decoupling control and the pre-swing control are proposed and numerically simulated. Experiments demonstrate that the two methods have validity and robustness. Some conclusion with significances in engineering are got by analyzing the simulation results.
