Identification and Control for High-performance Synchronous Reluctance Motor Drives

Description

Due to growing environmental concerns and current trends towards magnet-free electric motors that do not require rare-earth elements, synchronous reluctance motors (SyRMs) are gaining considerable interest from industry and academia. Owing to low cost, rotor robustness, and high efficiency compared to induction machines SyRMs are promising candidates for a wide range of applications that can meet current and future efficiency standards. As SyRMs exhibit highly nonlinear current-to-flux linkage relationships due to the magnetic saturation and cross-saturation phenomena, accurate knowledge of the magnetic model is of paramount importance for the control of SyRMs. Therefore, the first part of the Ph.D. project deals with magnetic model identification methods, focusing on reducing the identification time and considering the high-order harmonics of flux linkages to establish a high-fidelity model. One key factor hindering the application of SyRMs is the high torque ripple generated by the interaction between the spatial harmonics of the stator magneto-motive force and the rotor saliency. To address this issue, the second part of the Ph.D. project investigates torque ripple reduction by means of the d-axis, q-axis, and dq-axes current harmonics injections (CHIs) with particular focus on induced iron loss due to CHI to emphasize its importance for the total losses minimization of SyRM
