<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...

The SRM drive operates over the entire speed range and provides low torque ripple with smooth transition between the control operations. The low torque ripple is achieved by controlling the firing angles through simple formulas so as to minimize the pulsations of the total current in the commutation region. The smooth transition is attained since the conditions that determine the firing angles ...

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...

Brushless Direct Current (BLDC) motors are widely used due to high reliability, simple frame, straight forward control, and low friction. BLDC motor has the advantage of high speed adjusting performance and high power density. Speaking of the motor drive control, the most important part is commutation control. On the other hand, they show a high torque ripple characteristics caused by nonideal ...
