基于卡尔曼滤波的H∞控制策略提升并联有源电力滤波器性能

This paper proposes a Kalman filter (KF)-based H∞ control scheme for a three-phase shunt active power filter (SAPF) system. For the current control loop, a H∞ controller is designed with a mixed sensitivity approach for achieving stability and high-disturbance rejection in the SAPF system. A new current reference scheme is also proposed that employs KF to avoid synchronization circuit and proporti...
