摘要
为提高光伏储能系统的控制性能和抑制外部干扰的能力,提出了一种自抗扰控制策略,即在电流内环采用双向变换器线性自抗扰控制策略,在电压外环采用模糊自抗扰控制策略.利用Matlab/Simulink仿真平台对传统PI、 LADRC控制器与基于模糊控制的LADRC (fuzzy-LADRC)控制器进行仿真对比表明,fuzzy-LADRC控制器可有效抑制因多源干扰而引起的直流母线电压波动,并可提高光伏系统的跟踪性能和鲁棒性.
In order to improve the control performance and mitigate external disturbances of photovoltaic energy storage systems,a self-disturbance rejection control strategy was proposed.Specifically,a bidirectional converter linear self-disturbance rejection control strategy was employed in the current inner loop,while a fuzzy self-disturbance rejection control strategy was utilized in the voltage outer loop.The use of Matlab/Simulink simulation platform was employed to compare the performance of the traditional PI and LADRC controllers with the fuzzy control-based LADRC(fuzzy-LADRC)controller.The simulation results demonstrate that fuzzy-LADRC controller can effectively overcome the problem of DC bus voltage fluctuation caused by multiple sources of interference,and improve the tracking performance and robustness of the photovoltaic system.
