摘要

为了可靠地验证姿态确定和控制系统，地面硬件在环仿真是非常必要的。为此，博洛尼亚大学开发了一个三自由度立方体卫星动态试验台。本文介绍了一种1U立方体卫星测试平台的开发。在设施内，确保无干扰的环境，并由亥姆霍兹笼产生磁场，以实现磁姿态控制系统的实验验证。集成了COTS立方体卫星模型，仅依靠磁致力矩器测试了坠落、自旋轴指向和三轴姿态控制律。实验结果表明，该装置能够满足高要求的磁姿态控制要求。

On-ground experimental verification of magnetic attitude control for nanosatellites

For reliable verification of attitude determination and control systems, ground-based hardware-in-the-loop simulations are strongly desirable. To this end, a Three-Degrees of Freedom Dynamic Testbed for CubeSats has been developed at the University of Bologna. In this paper, the development of a platform for 1U CubeSats testing is described. Within the facility, disturbance-free environment is guaranteed and a magnetic field is generated by a Helmholtz cage to enable experimental verification of magnetic attitude control systems. A COTS CubeSat mockup is integrated and employed to test detumbling, spin-axis pointing and three-axis attitude control laws relying on magnetorquers only. The experimental results show the facility capabilities in highly demanding magnetic attitude control scenarios.
