摘要
高空气球标定的太阳能电池是可被用于地面太阳模拟器和太阳光光强检测的标准电池。首先,给出了由飞行气球搭载的高空太阳能电池标定所使用的太阳跟踪控制系统设计方法,包括基于STM32的太阳跟踪控制系统硬件设计方案、混合自动追踪控制策略、软件开发与实现方法、高空跟踪控制技术问题解决方案以及高空标定试验等。同时,解决了高空气球电池标定用太阳跟踪控制系统在极端环境下高可靠性、连续追踪和防抖动等关键技术问题。试验结果为气球飞行高度32km,平飘时间超过2h,太阳跟踪偏差小于1°。经初步分析,高空太阳跟踪控制系统标定测试结果合理可靠,工作性能稳定,为中国高空气球太阳能电池AM0标定用太阳跟踪控制系统的研究提供了新思路。
The high-altitude balloon calibration solar cell is the standard cell which can be used for the ground sun simulator and light detection.This paper presents a control method of sun tracking for solar cell calibration at a high altitude by the flying Balloons.The paper gives the design of hardware and software of the solar tracking,hybrid automatic tracking control strategy,altitude tracking control problem solving,and the result of solar tracking in high-altitude simulation environment test.Mearwhile,the key technical problems in the high-altitude ballon calibration solar cell tracking control system under extreme environment is solved,such as reliability,continuous tracking and anti-shake in extreme environments.In the experiment,the balloon flight level is 32 km,flying time is more than 2 h,and the deviation of solar tracking is less than 1°.A preliminary analysis shows that the results of solar calibration test are reasonable and reliable,which provides a new idea for the study of high-altitude balloon AM0 solar cell calibration with sun tracking control method.
