Special Section on Modern control of drives and power converters)}, journal={Bulletin of the Polish Academy of Sciences Technical Sciences}, pages={983-995}, howpublished={online}, year={2020}, abstract={In this paper an application of extended Kalman filter (EKF) for estimation and attenuation of periodic disturbance in permanent magnet synchronous motor (PMSM) drive is investigated. Most types of disturbances present into PMSM drive were discussed and described. The mathematical model of the plant is presented. Detailed information about the design process of the disturbance estimator was introduced. A state feedback controller (SFC) with feedforward realizes the regulation and disturbance compensation. The theoretical analysis was supported by experimental tests on the laboratory stand. Both time- and frequency-domain analysis of the estimation results and angular velocity were performed. A significant reduction of velocity ripple has been achieved.}, type={Article}, title={Application of extended Kalman filter for estimation of periodic disturbance and velocity ripple reduction in PMSM drive}, URL={http://ochroma.man.poznan.pl/Content/117682/PDF/04_D983-995_01565_Bpast.No.68-5_30.10.20_.pdf}, doi={10.24425/bpasts.2020.134649}, keywords={extended Kalman filter, disturbance estimation, PMSM drive, pulsating torque, velocity ripple reduction}, }
