太阳能“程控+光控”跟踪误差校正分析

摘要

This paper expounds the principle and structure of“programme+light control”tracking control system, establishes a systemetic mathematical model which take the condenser starting and ending angle error as control system’s input signal, analyzes and determines the photoelectric detector error correction device and its relevant parameter. Furthermore, in envi-ronment of MATLAB software the photoelectric detector error correction is analyzed and emulated. The results show that the photoelectric detector error correction can effectively improve the solar tracking system accuracy, which provides a basis on development of high precision solar tracking control system.%阐述了“程控+光控”跟踪控制系统的原理与结构，建立以聚光器始末角度误差值作为跟踪系统输入信号的数学模型，对比分析了光电探测器的误差校正系统并确定了相应的参数，在软件MATLAB环境中进行了光电探测器的误差校正数值分析与仿真。结果表明跟踪系统经过光电探测器的误差校正能够有效提高跟踪精度，提高光能利用率，所作研究分析为高精度的太阳能跟踪控制系统的开发利用提供理论依据。
