“…The sensorless control methods are not only used for low-speed control but also the motors can be controlled in the entire speed range with these methods. Lack of speed sensor downsizes the system and saves space, costs less, eases the implementation of the drive, provides a more reliable system, and gives more flexibility to the system design for environmental compatibility, while it imposes complexity to the control [122,[168][169][170][171].…”

“…The SynRM's parameters, and in particular inductances, are more likely to change under the iron saturation situation. Therefore, among FW operation concerns, the robustness of the controller against parameter variations of SynRMs as well as external disturbances are vital considerations [170,200]. In Reference [132], a robust FW algorithm for the DTC algorithm has been presented for the DTC of SynRM.…”

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.

“…The electrical motor must meet the power factor standards to use industrial applications [21]. However, LS-SynRM has a lower power factor than IM and LSPM because of a saliency characteristic and may not meet the power factor standards [22][23][24]. Therefore, the design method considering the power factor is required.…”

As international regulations of motor efficiency are strengthened, the line-start synchronous reluctance motor (LS-SynRM) is being studied to improve the efficiency of the electrical motor in industrial applications. However, in industrial applications, the power factor is also an important performance index, but the LS-SynRM has poor power factor due to the saliency characteristic. In this paper, the rotor design of LS-SynRM is performed to improve the efficiency and power factor. First, the barrier design is performed to improve the efficiency and power factor using the response surface method (RSM). Second, the rotor slot design is performed according to the length of bar for synchronization. Lastly, the rib design is performed to satisfy the power factor and the mechanical reliability. The final model through the design process is analyzed using finite element analysis (FEA), and the objective performance is satisfied. To verify the FEA result, the final model is manufactured, and experiment is performed.

“…In the last few years, sensorless speed control algorithms have drawn the researcher's attention in both industry and academia [14][15][16][17][18][19][20][21][22]. A simple and robust rotor estimation technique is proposed in [14], in which the position estimation is based only on the rate of change of stator currents and there is no effect of other parameters.…”

This study deals with a two-stage photovoltaic (PV) array-fed irrigation pump using a synchronous reluctance (SynREL) motor drive. In this scheme, a boost converter is utilised for harvesting maximum available power from a PV array through an incremental conductance-based maximum power point tracking algorithm. Here, it feeds power to a voltage source inverter through a DC-link capacitor. The prime objective of the proposed system is to provide water supply for domestic and irrigation purposes; therefore, to avoid complexity and for increased reliability, the speed/position sensor is eliminated. A speed/ position observer is utilised for the estimation of angular position of SynREL motor. A PV feed-forward term is used to estimate the reference speed, which aids in enhancing the transient behaviour of proposed system. Moreover, the control is inherently resistant to the ageing-related variation in pump's constant. The applicability of proposed water pumping system is verified through test results, recorded on a developed prototype in the laboratory under varying atmospheric conditions.
