| 中文摘要 | 姿态测量是飞行器实现自主导航的前提条件。针对单轴红外地平仪在飞行器姿态绝对测量中存在盲区的问题,提出了利用两轴红外地平仪进行全范围角度测量方案。在待测姿态角平面内,将地平仪两轴垂直放置,通过判断转动过程中两组传感器所在的象限位置,利用两轴必有一轴工作在非盲区的特点,合理选取输出量进行转角解算。解算结果和实验设定转角进行比较,二者静态偏差小于1°,能实现360°全范围角度测量。两轴红外地平仪全范围角度测量克服了单轴红外地平仪角度测量范围的局限性,对飞行控制中姿态角反馈具有重要意义。; Attitude detection is a key part of automatic navigation control system.The two-axes infrared horizon is an absolute detection methodology which avoids blind areas that occur with the single infrared horizon technique.The two axes are placed perpendicular to each other in the attitude plane with one in the measurable area.The attitude is then calculated based on the quadrants with errors of less than 1�The two-axis infrared horizon method provides a full range of 360�and overcomes the localization inherent in the single axes infrared horizon detector.Therefore,this methodology is much more related and effective for automatic control systems. |
