摘要
由于光伏电池的能量密度和转换效率相对较低,且其输出功率受光照强度和环境温度影响较大,需要动态调整输出功率,以保证光伏电池的最优功率输出。针对光伏电池的使用特性,提出自抗扰控制(ADRC)技术,并设计一种基于一阶ADRC技术的最大功率点跟踪(MPPT)控制器,以快速确定光伏电池的最优输出功率,缩短系统调节时间,提高跟踪速率;为验证设计的自抗扰控制器的跟踪效果,构建光伏电池充电的数学模型,采用Matlab/Simulink进行仿真验证。结果表明,加入一阶自抗扰控制的MPPT控制器能够快速准确地跟踪最大功率点。
Because the energy density and conversion efficiency of photovoltaic cells are relatively low,and its output power is greatly affected by the light intensity and ambient temperature,it is necessary to dynamically adjust the output power to ensure the optimal power output of photovoltaic cells.According to the application characteristics of photovoltaic cells,ADRC technology is proposed,and a maximum power point tracking(MPPT)controller based on first-order ADRC technology is designed to quickly determine the optimal output power of photovoltaic cells,shorten the system adjustment time and improve the tracking rate.In order to verify the tracking effect of the designed active disturbance rejection controller,a mathematical model of photovoltaic cell charging was constructed and verified by Matlab/Simulink.The results show that MPPT controller with first order active disturbance rejection control can track the maximum power point quickly and accurately.
