The control of (PMSM) is the subject this study and torque ripple reduction in main goal work. Torque flux are controlled using a predictive model Vector Control. Because it commonly employed regulating electric motors. Space vector two approaches used study. Predictive was determined to be more effective terms response action after Matlab simulation approaches. MPC covers all potential switchi...
<span lang="EN-US">The induction motor is extremely well known and used as an alternating current (AC) machine. Therefore, torque speed regulations are very essential for this type of This paper presents direct control (DTC) based on motors (IM). The mathematical model IM reported, the machine modeled in a synchronous coordinate farm. Classic DTC applied to with two bandwidths hysteresis ...
Direct torque control (DTC) of Switched reluctance motor is known to have simple control structure with comparable performance to that of field oriented control techniques. However, the role of optimal selection of the voltage space vector is one of the weakest points in a conventional DTC drive. In this paper optimal selection of voltage space vectors is achieved using neuro fuzzy controller. ...
-Among all the speed control techniques for induction motor drives, Direct Torque Control (DTC) method is simple and efficient because DTC is independent of machine rotor parameters and free from d-q transformation. Modern DTC based drives are equipped with estimators, observers, and machine intelligence systems to improve the dynamics and efficiency of the drive. This paper is aimed to focus o...
Magnetic gears offer significant advantages such as low noise and vibration level, lower maintenance higher reliability compared to mechanical are suitable for many applications in the industry. The coaxial magnetic gear has been extensively discussed literature, since it achieves torque densities amongst other configurations. field is generated by permanent magnets mounted on two rotors a modu...
Abstract-Voltage sag or unbalance conditions at the input rectifier stage of the ac-dc-ac rectifier-inverter induction motor drive can cause the significant amounts of harmonic voltage at twice the line frequency 2f1. This voltage ripple can have a degrading effect on the induction-machine performance characteristics. This paper presents an analytical closed-form mathematical model and analysis...
Electric Power Steering system provides the assist steer torque in vehicle through an electric motor. Since the electric motor is directly connected to the mechanical steering rack, must have the following features: Torque production with minimum Ripple for Precise steer control, High efficiency, easy Manufacturing technology and minimum size and weight. Motor structure optimization is done in ...
