ADRC-Based Controller with Linkage Compensation for Interleaved Parallel Converters
2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)(2023)
Abstract
The microgrid is the key development direction of distributed energy. However, the performance indicators of its low-voltage side interface are often affected under complex operating conditions. To address this problem in a targeted manner, a linkage compensatory active disturbance rejection controller (LC-ADRC) that considers both the higher-order perturbation model and object model information is proposed. In this work, the extended state observer (ESO) and the feedback control law of the LC-ADRC are reconstructed according to the interleaved parallel bi-directional converter (IBC) characteristics, and the theoretical analysis shows that the dynamic response and immunity to disturbances of the IBC under typical conditions can be improved simultaneously. Finally, the experimental curves and test indexes obtained from the 300-watt test platform designed for these operating conditions verified the accuracy of the theoretical analysis.
