Research on Motion Control of Three Degree of Freedom Automatic Chasing System for Automotive Solar Cells

为了让太阳能电池在电动汽车上高效应用,设计自动追光系统的三自由度机构,通过摄像头采集阴影中心点坐标用来获取太阳光的照射方向,使用几何运算并通过最小二乘法求解得到电机的旋转角度,对电机进行驱动。建立系统的仿真模型,仿真结果证明了系统较为稳定,并能使太阳能电池板法线与太阳光线保持一致,提高了能量利用效率。

In order to achieve efficient application of solar cells in electric vehicles,the three-degree-of-freedom mechanism of the automatic light chasing system is designed,the coordinates of the shadow center point are collected by the camera to obtain the irradiation direction of sunlight,and the rotation angle of the motor is obtained by geometric operation and solved by the least squares method,and the motor is driven.The simulation model of the system is established,and the simulation results show that the system is relatively stable,and the normal of the solar panel can be consistent with the sun's rays,which improves the energy utilization efficiency.
