A Direct Model Predictive Control Strategy for High-Performance Synchronous Reluctance Motor Drives

Abstract

This paper presents a finite control set model predictive control (FCS-MPC) method that improves the performance of a synchronous reluctance machine drive. As shown, when a high sampling-to-switching frequency ratio is used with FCS-MPC, the stator current distortions can be significantly reduced, allowing for less losses in the machine. Moreover, the FCS-MPC steady-state performance is enhanced by introducing an integrating element into the cost function to ensure accurate output reference tracking. Finally, the adopted drive model that relies on an identified accurate magnetic model of the machine further improves the robustness of the discussed control scheme. The presented simulation and preliminary experimental results verify the effectiveness of the discussed method.

Model-free control-based vector control of synchronous reluctance motor

“…An adaptive inductance estimation technique for vector-controlled SynRM drive is presented in [35]. In [36] similar to [34], a finite control set model predictive control method has been developed to improve the performance of a SynRM drive. The authors of [37] have presented model predictive control of SynRM drive configured in open-end winding.…”
