International Journal of Circuit Theory and Applications, Volume 53, Issue 7, Page 3970-3992, July 2025.For the series active filter (SAF), a combined controller and observer scheme is proposed. Two controllers—state feedback (SFB) and linear quadratic regulator (LQR)—along with state observers, including the Luenberger observer (LO), proportional–integral observer (PIO), and unknown input observer (UIO), have been designed.
