Abstract

To address the issue of deteriorating power quality in photovoltaic microgrid demand-side converters caused by complex uncertain disturbances, a corrective active disturbance rejection control （ADRC） strategy integrating adaptive rules is proposed. First, the disturbance observation transfer function of the linear extended state observer part is corrected to avoid certain errors at steady state, enabling more accurate tracking of total disturbances. Second, rule-based design is used as a parameter optimization mechanism to adjust the outer-loop controller parameters online in real time, further optimizing the system's speed and accuracy performance. Then, based on theoretical derivations regarding the total disturbance reconstruction capability and disturbance suppression ability, the internal rationale for how the proposed strategy can effectively enhance system control quality is pointed out, and the system stability is proved using the Leonard-Chipart stability criterion. Finally, the effectiveness and feasibility of this strategy are verified through digital simulation results and robustness analysis under parameter perturbations.
