由于太阳位置随时间而变化，使光伏发电系统的太阳能电池阵列受光照强度不稳定，从而降低了光伏电池的效率，因此，设计太阳自动跟踪器是提高光伏发电系统工作效率的有效措施。该文针对已有的光伏跟踪控制方法的缺陷与不足，考虑到执行电机在转动时间内对太阳位置角度的变化与跟踪误差范围的预测与控制，提出了一种采用PLC的跟踪控制方法，并通过理论分析与Matlab/Simulink仿真结果验证了其可行性，具有很高的推广应用价值。

As the position of the sun changes with time, the light intensity of the solar cell array of photovoltaic power generation system is not stable, therefore the efficiency of photovoltaic battery is re-duced. So, the design of automatic solar tracker is the effective measures to improve the efficiency of photovoltaic power generation system. Aiming at the existing defects and shortcomings of the photovoltaic tracking control method, the author takes into account the prediction and control of motors in the rotation time variation of solar position angle and tracking error range, proposes a tracking control method using PLC, and has tested its feasibility by theoretical analysis and simulation results in Matlab/Simulink.
