A Novel Model Predictive Control for Torque Pulsations Suppression of Variable Flux Memory Machine During Magnetization State Manipulations

This paper proposes a novel sliding-mode model predictive current control (SM-MPCC) to tackle the issue of large torque pulsation during magnetization state (MS) manipulations in variable flux memory machine (VFMM) drives. The proposed control system integrates the sliding-mode control (SMC) with model predictive current control (MPCC), which are utilized in the outer speed and the inner current controllers, respectively. In comparison to the traditional controllers, this innovative SM-MPCC makes better use of the reaching law to track the transient variables of VFMM, thus highly improving the dynamic and steady-state performance of the drive system. The simulated results are presented for the feasibility validation of the proposed control strategy.
