摘　　要：为了提高太阳能的利用率,选取合适的视日轨迹跟踪算法显得尤为重要。以江苏徐州为例,借助Matlab软件对视日轨迹跟踪的5种常用赤纬角近似算法和4种太阳时差近似算法进行仿真分析,结果表明:基于Cooper的太阳赤纬角近似算法并非最优,而Spencer近似算法计算出的太阳高度角和方位角误差最小,更能提高视日轨迹跟踪的准确度。In order to improve the utilization rate of solar energy, it is very important to select a suitable trajectory tracking algorithm. Taking Xuzhou, Jiangsu Province as an example, five common algorithms of declination angle and four kinds of approximate algorithms of solar time difference are simulated and analyzed by Matlab software. The results show that the approximate algorithm of solar declination angle based on cooper is not optimal, while the error of solar altitude angle and azimuth angle calculated by Spencer approximation algorithm is the smallest, which can improve the accuracy of solar trajectory tracking.
