摘要
对太阳能利用中的开环、闭环和混合控制跟踪控制方式的特点进行了分析。通过计算几种单轴跟踪方式的跟踪角 ,根据跟踪角和太阳的时角间的关系 ,对单轴跟踪时的控制方式的选择进行了研究。特别是使用了MATLAB程序处理数据 ,得到南北水平轴跟踪时跟踪角和太阳时角间的关系图像 ,着重分析了此时采取混合跟踪的可行性和适用性。对几种跟踪控制方式的优缺点进行了分析和总结 。
This paper sorts tracker controller methodologies in utilization of solar energy into close loop, open loop, and hybrid. Solving and substituting into the equation, the tracking angle of several single\|axis tracking modes can be gained. By relations between hour angle and the tracking angle of several single\|axis tracking modes, selecting for controller methodologies of several single\|axis tracking modes are acquired. By using MATLAB to deal with data, the figures of relations between hour angel and the tracking angle of horizontal N/S tracking can be worked out, and at this time feasibility and applicability of hybrid tracking control system are analyzed. Merits and demerit of several tracker controller methodologies are studied and summarized, and characteristic and applicability of them are researched.
