摘要

摘要: 大型空间薄膜天线在深空探测、天基预警、对地观测等领域具有广阔的应用前景.由于薄膜天线具有大、轻、柔的显著特征，其动力学与控制问题十分复杂且突出.与此同时，由于天线工作性能的需求，天线在轨运行时必须保持极高的指向精度和形面精度.这就要求我们对薄膜航天器进行精细的动力学分析与有效的主动控制设计.该文针对一类平面张拉式薄膜天线进行刚-柔-热耦合动力学建模与复合控制问题的研究.首先，基于非线性有限元方法建立了薄膜天线结构的非线性动力学模型，并对该模型进行了模型降阶.然后，基于非线性降阶模型并考虑空间热环境的影响，采用混合坐标法建立了航天器的刚-柔-热耦合动力学模型.最后，采用合力合成控制方法结合拉索作动的非线性振动控制策略，对航天器的姿态运动和非线性振动进行了同步、复合控制.

Abstract: Large space membrane antenna has a great prospect in the fields of deep space exploration, space-based early warning and earth observation. Due to the large-size and high-flexibility of the membrane structure, the membrane antenna spacecraft poses challenging dynamic and control issues. Meanwhile, to maintain the working performance of the antenna, the pointing accuracy and surface accuracy must be kept strictly. Therefore, accurate dynamic modeling and effective active control of large membrane antenna are of great significance and practical interest, and attract a lot of attentions in recent years. The rigid-flexible-coupling dynamics and hybrid control of membrane antenna spacecraft were studied. First, based on the nonlinear finite method the nonlinear dynamic model for the membrane antenna structure was established, and the nonlinear dynamic model order reduction was also studied. Then, in view of the thermal flux, the rigid-flexible-thermal coupling dynamic model for the spacecraft was established by means of the hybrid coordinate method. With the component synthesis vibration suppression method and the cable-actuator-based nonlinear vibration control method, a hybrid control system was designed to control the attitude motion meanwhile reduce the nonlinear vibration.
