基于模型辅助准比例谐振扩张状态观测器的单相构网型逆变器电压控制
Voltage control of single-phase grid-forming inverters based on a model-assisted extended state observer with a quasi-proportional resonant controller
摘要
Abstract
To address the limitations of conventional extended state observers(ESOs),which suffer from bandwidth constraints leading to poor estimation of sinusoidal signals and low utilization of system models,a novel model-assisted quasi-proportional resonant extended state observer(MA-QPRESO)-based active disturbance rejection control(ADRC)scheme is proposed.Specifically,the quasi-proportional resonant control is embedded into the ESO to improve its capability for estimating sinusoidal signals,while model-assisted compensation is introduced to account for known disturbances,thereby reducing the observer burden.Subsequently,the disturbance rejection performances of the proposed MA-QPRESO and the conventional ESO is compared through frequency-domain analysis to theoretically demonstrate the superiority of the proposed method.Finally,the effectiveness of the proposed method is verified by experiments on a single-phase grid-forming inverter.The method achieves robust control under variations in electrical parameters while maintaining excellent steady-state and dynamic performance.关键词
