The induction motors are indispensable motor types for industrial applications due to its wellknown advantages. Therefore, many kind of control scheme are proposed for induction motors over the past years and direct torque control has gained great importance inside of them due to fast dynamic torque response behavior and simple control structure. This paper suggests a new approach on the direct...

Electric vehicle (EV) due to its running zero emission, sustainability and efficiency is of interest for future transportation. In-wheel technology has been one of the main research concentration points in last decade. BLDC motor is on demand for in-wheel application because of its high efficiency, torque/speed characteristics, high power to size ratio, high operating life and noiseless operati...

In this paper, two intelligent direct torque control strategies are compared with the classical direct torque control (C-DTC) scheme, namely neural network control (NNC) and neuro-fuzzy control (NFC) are introduced to replace the hysteresis comparators and lookup table of the C-DTC for pulse width-modulation-inverter-fed induction motor drive, to solve the problems of torque ripple and inconsta...

This paper considers direct torque control strategies in induction motor drive to minimize torque ripples. Spacevector modulation and modified space vector control concept is implemented to design the controller. Basic DTC method suffers from torque ripples problem and switching frequency variation.[1] Torque ripples are minimized using space vector modulation technique but execution time in th...

a few papers have been interested by the fixed switching frequency direct torque control fed by direct matrix converters, where we can find just the use of direct torque controlled space vector modulated method. In this present paper, we present an improved method used for a fixed switching frequency direct torque control (DTC) using a direct matrix converter (DMC). This method is characterized...

In this paper, an improved immune algorithm (IIA) was proposed for the torque ripple reduction optimal design of interior permanent magnet synchronous motor (IPMSM) a fuel cell electric vehicle (FCEV) traction motor. When designing machines, both global and local solutions designs are required as result should be compared in various aspects, including torque, ripple, cogging torque. To lessen c...

Therefore, they are obtained wide applications from automotive to aerospace [1][2] . One of them is the five-phase PM machine, where the torque density can be improved by injecting third harmonic current . However, in order to maintain high torque density and re...

Abstract: A fault-tolerant permanent-magnet vernier (FT-PMV) machine incorporates the merits of high fault-tolerant capability and high torque density. In this paper, a new remedial control is proposed for a five-phase FT-PMV machine with short-circuit fault of stator windings. Based on the principle of copper loss minimization, the aims of the proposed control strategy are to keep magnetic mot...

The simple structure, low manufacturing cost, rugged behavior, high torque per unit volume and wide torquespeed range make switched reluctance motor (SRM) very attractive for industrial applications. However, these advantages are overshadowed by its inherent high torque ripple, acoustic noise, and difficulty to control. The controlled parameters in SRM drives can be selected as the turn-on angl...
