摘要
基于实现太阳能的最大利用,通常采用最大功率跟踪控制的方式来实现能量的捕捉和跟踪,最终实现最大效能的控制目标。阐述电导增量法、波动相关控制法、扰动观测法等三种最大功率跟踪控制方法,提出了可灵活调整的变步长扰动观测法,实现光伏电池在不同工作点的有效跟踪,从而提升控制的精度。
In order to achieve maximum power tracking and control,maximum power tracking is usually used.This paper mainly introduces three maximum power tracking control methods,including conductance increment method,fluctuation correlation control method and disturbance observation method.Finally,a flexible variable step size disturbance observation method is proposed to realize the effective tracking of photovoltaic cells at different operating points,so as to improve the control accuracy.
