“…At very low speeds, sensorless controls have gained attention [160,161]. In speeds up to nominal speeds, researchers mostly focus on maximum torque per ampere (MTPA) operation [162,163], while in speeds higher than nominal speed, FW is considered as a dominant approach for control [97,164] and MTPV has been implemented in speeds higher than crossover speed [165,166]. Generally, in SynRMs, the copper losses are dominant [51].…”

“…Regarding direct torque and flux control of DTC, this method can serve as the best choice for FW operation. However, FOC-and MPC-based MTPV operation algorithms of SynRM in the FW region can be found in the literature [140,165,197,198]. Due to the sensitivity of current vector control to the orientation errors in the MTPV region, such as encoder offset, any angle error can result in undesired torque reversal.…”

Recent studies show that synchronous reluctance motors (SynRMs) present promising technologies. As a result, research on trending SynRMs drive systems has expanded. This work disseminates the recent developments of design, modeling, and more specifically, control of these motors. Firstly, a brief study of the dominant motor technologies compared to SynRMs is carried out. Secondly, the most prominent motor control methods are studied and classified, which can come in handy for researchers and industries to opt for a proper control method for motor drive systems. Finally, the control strategies for different speed regions of SynRM are studied and the transitions between trajectories are analyzed.

However, VCC is the most common one [31]- [38]. These methods may also be divided into three type of regulation: on the voltage magnitude [32], [34], [36]- [38], on the voltage error [31], [35] and on the duty cycles [33].…”

This paper presents an enhanced Flux Weakening (FW) control scheme for Permanent Magnet Synchronous Motors (PMSMs), focused on electric vehicle applications. The novelty of the proposed algorithm is the integration in a unified scheme of both the accelerator pedal as torque reference and the cruise speed limiter (CSL) as speed limit, without interfering between them until this limit is achieved. The dq-axis current references are calculated from the proposed algorithm by using a polar coordinate system and a per-unit system. The latter is based on the characteristic machine parameters which aim to ease and simplify the algorithm implementation. Moreover, it takes advantage of the smooth transition between the Low Back Electromotive Force (LBEF) zone and the FW zone thanks to a voltage loop which changes the current-vector angle. Another fundamental merit of the proposed scheme is its capacity to work in all the dq-plane throughout the Maximum Torque per Ampere (MTPA), Constant Torque (CT), Current and Voltage Limit (CVL), Maximum Torque per Voltage (MTPV) and Constant Speed (CS) strategies without switching the algorithm. Simulations and experimental results from a real exterior-rotor Interior Permanent Magnet Synchronous Motor (IPMSM) direct-drive emotorbike verify the effectiveness of the proposed method.
