In this study, a high-power synchronous reluctance motor (SynRM) was designed for the traction motor of electric vehicle (EV) and its double-stage optimization was performed. Genetic algorithm and sensitivity analysis methods were used to obtain the best design parameters of the SynRM. Double-stage optimization was carried out to minimize the torque ripple and obtain the targeted torque, speed, and power values of the SynRM. In the first stage, the genetic algorithm method was used to improve the design parameters of the stator and rotor. With the improved stator and rotor design parameters obtained using this optimization technique, it was observed that the torque ripple decreased. In the second stage, the sensitivity analysis method was used. In this method, the effect of changing the skew angle of the stator on the torque ripple was investigated. The magnetic and performance analyses of the designed motor were examined in the optimization process. Analyses were made by ANSYS Maxwell using the finite element method (FEM). It has been observed that the targeted torque, power, speed, efficiency, and torque ripple minimization values are successfully achieved when the performance analysis of the motor is performed using the best stator and rotor parameters obtained through optimization. The results showed that SynRM produces high torque and high power with high efficiency and low torque ripple over a wide speed range. It has been revealed that it is quite proper to use the designed SynRM as a traction motor of new generation electric vehicles.

“…Recently, the Synchronous Reluctance Motor has emerged as a promising substitute for conventional 3-PH induction motors and permanent magnet synchronous motors in variable speed applications that prioritize high efficiency, cost-effectiveness, and reliability. This motor exhibits numerous advantages, including the absence of rotor windings and permanent magnets, a sturdy rotor construction, no excitation necessity, negligible speed regulation, superior power density, and heightened efficiency [1][2][3][4][5]. Furthermore, its pricing is comparable to that of induction motor drives, making it a competitive option in terms of cost [6,7].…”

This paper presents the utilization of a fuzzy logic controller (FLC) within the speed control loop of the direct torque control (DTC) algorithm. The aim is to enhance the dynamic performance of a 3-phase synchronous reluctance motor (SynRM) in variable speed applications. The proposed FLC employs the speed error and change of speed error to generate the torque command signal needed for the torque hysteresis comparator within the DTC scheme. The system being analyzed comprises of a synchronous reluctance motor, voltage source converter and the proposed fuzzy logic-based DTC. In order to evaluate the performance of the proposed controller, a comprehensive system model is developed and simulated using MATLAB Simulink. The dynamic response of the entire system is investigated when subjected to various command speeds and loading conditions. It is found that the proposed controller achieves fast and precise dynamic response under all operating conditions. Furthermore, a comparative analysis is conducted between utilizing the FLC and the traditional proportional integral differential (PID) controller in the speed control loop of the DTC, the results demonstrate a significant improvement in the dynamic response when employing FLC compared to the traditional PID controller.

PV irrigation systems have begun to be used intensively today, as energy needs increase. In Partially Shaded Conditions (PSC), the efficiency of the PV system decreases significantly, and traditional Maximum Power Point Tracking (MPPT) algorithms become insufficient. On the other hand, traditional MPPT algorithms require sensors to measure the current and voltage of the PV system. In this study, a sensorless hybrid MPPT algorithm is proposed to reduce system costs and enable operation without the need for PV system data. A simulation study was conducted in the MATLAB/Simulink environment to examine the PV system. The proposed algorithm has been tested under four different PSC scenarios. PV system power, motor speed, and currents were examined under each condition. The high maximum power tracking performance of the proposed algorithm is demonstrated through simulation results. In the steady state, the lowest MPPT efficiency was 95.66%, whereas the highest MPPT efficiency was 99.9%. The MPPT algorithm completed in less than 2 seconds, with the first stage taking 1.3 seconds to reach most of the maximum PV system power. The second stage of the MPPT algorithm was used to achieve maximum power in a narrower area.
