Active Disturbance Rejection Controll Strategy with Lead Compensation and Feedforward

Abstract An active disturbance rejection controll Strategy with lead compensation and feedforward (ADRC-LCF) is proposed to address the problem of poor power quality at output direct-to-direct converter when microgrid subject uncertain disturbances. The control strategy achieves reconstruction self-anti-disturbance controller by connecting over-compensator in series introducing differential feedforward, which effectively improves suppression performance controller. Finally, numerical simulations comparing different operating conditions show that recovery time ADRC-LCF reduced about 70% 58% compared PI LADRC respectively face load shedding; maximum overshoot 81% a sudden increase bus voltage.
