Improved model predictive control based on Luenberger state observer for LC‐coupling hybrid active power filter

Electronics Letters, Volume 60, Issue 13, July 2024.
An improved model predictive control with Luenberger state observer is proposed for LC‐coupling hybrid active power filter. This article utilizes the Luenberger observer to mitigate the steady‐state error without additional sensors, and the one‐sampling‐time delay compensation is given for the digital control delay.
