本文介绍了一种简单的气球姿态控制系统。该系统的目标是，对于直径为1.5米、惯性矩为100 kg·m2的小型有效载荷，实现0.1度的方位精度。它将首先与高能X射线偏振测量（PHENEX）实验一起飞行，该实验旨在观察硬X射线能量区域的天文物体的偏振。该系统由姿态传感器（太阳敏感器、地磁方位传感器和光纤陀螺）、读出模块、CPU、输出模块（基于PC104的板）和执行机构（扭矩释放电机和反作用轮电机及其驱动器）组成。本文在介绍了这些模块之后，将对基于地面的传感器和控制系统的特性进行综述。
A simple attitude control system for a balloon experiment has been developed. This system aims to achieve an accuracy of 0.1 deg in azimuth for a small payload with a diameter of 1.5 m and a moment of inertia of 100 kg·m2. It will be first flown with the Polarimetry for High ENErgy X-rays (PHENEX) experiment, which is to observe the polarization of astronomical objects in the hard X-ray energy region. The system is composed of the attitude sensors (sun sensors, geomagnetic aspect sensors, and an optical fiber gyro), read-out modules, CPU, output modules (PC104 based boards), and actuators (a torsion relief motor and a reaction wheel motor with their drivers). In this paper, after introducing these modules, the properties of the sensors and the control system based on the ground will be reviewed.
