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...

Abstract Switched reluctance motor (SRM) is paid more attention in industrial usage because of its simple structure and low cost. But the inherent torque vibration situation noise caused by limited application electrified vehicles, which requests sooth output. To meet demand minimizing ripple, this article presents a new direct control (DTC) method with changeable reference flux steady switchin...

Direct torque control (DTC) minimizes the use of machine parameters [1, 2]. Among all methods of torque control in induction motor, direct torque control (DTC) seems to be particularly interesting being independent of machine rotor parameters and requiring no speed or position sensors [3, 4, 5]. In spite of its simplicity, DTC is capable of generating fast torque responses. In DTC the torque an...

Direct Torque Control of Permanent Magnet Synchronous Motors With Non-Sinusoidal Back-EMF. (May 2008) Salih Baris Ozturk, B.S., Istanbul Technical University, Istanbul, Turkey; M.S., Texas A&M University, College Station Chair of Advisory Committee: Dr. Hamid A. Toliyat This work presents the direct torque control (DTC) techniques, implemented in fourand six-switch inverter, for brushless dc (B...

The matrix converter system is competitive solution to replace the conventional two stage ac to ac converter. In this paper, a matrix converter driving a speed-controlled induction machine is examined under open-switch fault. First, a-predictive direct torque method is proposed using only the motor torque and current. Second, a motor speed control is presented. The proposed techniques do not re...

Induction machine drive based on Direct Torque Control (DTC) allows high dynamic performance with very simple hysteresis control scheme. Conventional Direct Torque Control (CDTC) suffers from some drawbacks such as high torque ripple and variable switching frequency , difficulties in torque as well as flux control at very low speed. This paper is aimed to analyze DTC principles, the strategies ...
