摘　　要：对空间漂浮航天器太阳阵展开与锁定过程的刚柔耦合动力学与控制问题进行较为全面的研究。基于Jourdain速度变分原理和单向递推组集方法,建立了太阳阵展开与锁定过程的刚柔耦合多体系统动力学模型,采用模糊自适应PD控制方法对航天器本体的姿态扰动进行主动控制。通过对考虑柔性效应的太阳阵展开与锁定过程的数值仿真,较好地预测了太阳阵展开历程及航天器本体姿态扰动情况。另外,通过采用模糊自适应PD控制方法与传统PD控制方法进行仿真比较,验证了该控制方法对航天器姿态控制的有效性。The deployment and locking of solar arrays of the free-floating spacecraft is studied comprehensively in this paper.The rigid-flexible coupling dynamic model for describing the deployment and locking process is established using Jourdain′s velocity varitional principle and the approach of forward recursive formulation.The control design of the solar array system is discussed and the fuzzy adaptive PD control method is used for controller design.The deployment and locking process for solar arrays is well predicted through numerical simulation for the rigid-flexible coupling dynamic model.In addition,the effectiveness of the above control approach is verified by comparing the control results with the conventional PD control.
