“…While requiring a frequency converter with vector control for proper operation and being unable to directly connect to the grid (such as IM), SynRMs exhibit more desirable performance in variable speed applications, such as pumps, fans, compressors, and conveyors. Vector control, initially introduced by Hasse and Blaschke in the early 1970s, is a frequently utilized method for ac machine control, including SynRM [6]. By using a position sensor to synchronize the stator current vector with the rotor, SynRM can achieve remarkable performance.…”

The high-frequency injection (HFI) method is commonly used for sensorless control of synchronous reluctance motors (SynRMs) at low speeds. Injecting a high-frequency (HF) signal in a predefined direction, referred to as the d-axis, and further demodulating the excited signal in the q-axis are a popular sequence for SynRM position tracking. Injection in the q-axis is not usually considered due to its potential to increase torque ripple. This article proposes a generalized HF pulsating voltage injection approach for sensorless control of SynRM. This approach allows for the arbitrary selection of injection strategy and covers the injection and demodulation procedures in d-and q-axes in detail. Special attention is given to determining the amplitude of the injection voltage, which can extend the usage range of HFI and support sensorless control at high speeds. The effectiveness of the proposed structures is experimentally verified using 15 kW SynRM. During system validation, extra care is taken to investigate the overall system efficiency and vibration levels, including torque ripple issues. This solution contributes to the advancement of sensorless control for SynRM drives.INDEX TERMS High-frequency injection (HFI), motor efficiency, sensorless control, synchronous reluctance motor (SynRM), torque control, variable frequency drives.

This paper presents an Energetic Macroscopic Representation (EMR) of Electric Vehicles (EVs) with dual-motor allwheel drive (AWD). The dynamic process of the tire-road system is considered to provide the traction force for each wheel of the studied EV. The two traction motors of the studied system including the induction motor (IM) and the permanent magnet synchronous motor (PMSM) are detailed by dynamic models. The studied EV is organized to describe the model and to design the control scheme in a more convenient way using EMR. This model is used in simulation for studying the slip phenomenon of EVs in different scenarios. The traction force is presented and analyzed for a dual-motor vehicle.
