Iron-Loss Modeling With Sensorless Predictive Control of PMBLDC Motor Drive for Electric Vehicle Application

Permanent-magnet brushless dc motor (PMBLDCM) is more suitable for electric vehicle (EV) with higher torque and driving performance. A loss modeling of PMBLDCM proper analysis can improve the control stability at different road surface conditions. However, iron not minimal enough to be ignored during high-speed operation drives. This article proposes a disturbance observer-based sensorless drive accurate estimation rotor position. achieved by taking into consideration in order further reduce position error. modified model predictive also proposed deal novel provide ripple-free reduced losses. The EV performances are compared lossless through both simulation experimental validation.
