A Modified Deadbeat Predictive Flux Control for Reducing Torque Ripple at Low Modulation Ratio
2023 IEEE VEHICLE POWER AND PROPULSION CONFERENCE, VPPC(2023)
摘要
This paper proposes a modified accurate deadbeat predictive flux control (M-ADPFC) to reduce the torque ripple and improve the torque tracking accuracy at low modulation ratio. A torque ripple model with discretization error compensation and low computation burden is utilized to predict the torque ripple and tracking error in the space vector modulation (SVM) process. An optimization method based on the continuous-control set model predictive control (CCS-MPC) is proposed to minimized the torque ripple. Comparative simulations validate that the proposed method has reduced torque ripple and good tracking accuracy in a wide load range at low modulation ratio.
