Abstract

Large deployable membrane diffraction antenna plays a significant role in achieving high-precision remote sensing detection in the future owing to its super large aperture. In order to accurately adjust and maintain the primary mirror surface of the deployable diffraction antenna, a novel scheme of surface shape control has been proposed in this paper. In the scheme, the large deployable antenna is divided into several mirror units and each mirror unit is spread by braced frames. Besides, the membrane mounting units are controlled by six actuators with 6 degrees of freedom. The actuators which are low cost and applicable in complex environment are developed according to relevant control requirements. The designed actuators have the advantages of wide adjustable range (up to 21mm) and high precision (better than $0.16\mu m$), which is much better than the traditional piezoelectric actuator scheme, and the cost performance is higher than the adjustment scheme of optical telescope. Finally, the simulation results demonstrate the feasibility of the proposed control scheme. The performances of the actuators are displayed by experimental tests.

大型可展开膜衍射天线的表面控制

大型可展开膜衍射天线由于其超大孔径的特性，在未来实现高精度遥感探测中将发挥重要作用。为了精确地调整和保持可展开衍射天线的主镜面，提出了一种新的面形控制方案。该方案将大型可展开天线分成若干个反射镜单元，每个反射镜单元由支撑框架展开。膜安装单元由6个6自由度的执行机构控制。根据相关控制要求，研制出成本低、适用于复杂环境的执行机构。所设计的作动器具有可调范围宽(可达21mm)、精度高(优于0.16\mu m$)的优点，大大优于传统的压电作动器方案，性价比也高于光学望远镜的调节方案。最后，仿真结果验证了所提控制方案的可行性。通过实验验证了执行器的性能。
