摘要
介绍一种基于向日葵仿生原理的平行三轴阳光跟踪系统,实现对阳光的跟踪。首先,根据平行三轴跟踪原理,开展系统中主要参数对系统性能的影响分析;其次,在研制相应光学传感器的基础上,建立平行三轴追踪系统的实验测试平台;最后,利用测试平台开展相关实验,验证系统的有效性和可靠性。实验结果表明系统最佳追踪精度可达0.9°。
Based on the principle of sunflowers tracking the sun, a three parallel axes sun tracking （TPAST） system was developed. Firstly, the simulate model was built, by which the influence of the TPAST system＇ s main parameters was analyzed. Secondly, based on the optimized parameters of system, including supporting radius and the motor step length, the TPAST experimental system was built. Finally, the corresponding experiments were carried out, which verify the validity and reliability of the system. The results of experiments showed that the value of sun tracking accuracy is 0.90 degree in this system.
