摘　　要：针对目前太阳跟踪控制系统的抗干扰性能较差,无法买现目动的、买时跟踪控制等一系列问题,提出了一种基于FPGA的太阳能复合跟踪控制系统。该系统充分融合了视日运动跟踪和光电跟踪控制系统的优点,使用FPGA作为跟踪系统的主控器,在光照条件满足光电传感器要求的情况下采用光电跟踪,否则采用视日运动跟踪。实现了对太阳的高精度、全天候的跟踪控制,并最大限度地免除人为干预。实验结果表明,该跟踪控制系统可达到很好的跟踪效果。具有很大的实用价值。A compound system of solar tracking controller based on FPGA was proposed aiming at the problem that existing controller was sensitive to disturbing and couldn’t track automatically and real time.Merits of two exiting algorithms were mixed together.FPGA was used as a main controller that could select different pattern depending on different beam.A high precision and all-weather controller was obtained.Experimental results show that the tracking controller achieves a good tracking result and has a Great practical value.
