ABSTRACT
The present paper investigates the feasibility of utilizing the simplified prediction model for finite control set model predictive current
control (FCS-MPCC) applied to reluctance synchronous motors (RSMs). The FCS-MPCC exhibits torque and current ripples, and a
crucial consideration is the reduction of these ripples by increasing the switching frequency. The algorithm’s computational complexity
is tied to the accuracy of the adopted model. Two approaches with varying levels of accuracy in predicting current dependencies
concerning changes in the inductance of the RSM are investigated. The findings highlight the potential of employing simplified fixed
inductance values for efficient control in drive systems, particularly those amenable to high switching frequencies.
