Received Feb 16, 2017 Revised Apr 16, 2017 Accepted May 1, 2017 Numerous studies had been made to improve the switched reluctance motor operation depend on the modification of the machine design, proposing the converter designs and/or applying a suitable control method. This paper introduces the field orientation control method for that motor using a simple and very efficient DC-DC converter to...

This paper presents a comparative study on the Predictive Direct Torque Control method and the Indirect Space Vector Modulation Direct Torque Control method for a Doubly-Fed Induction Machine (DFIM) which its rotor is fed by an Indirect Matrix Converter (IMC). In Conventional DTC technique, good transient and steady-state performances are achieved but it presents a non constant switching freque...

The paper describes experimental results of a mediumvoltage, modular, 35 MW drive for Oil & Gas applications realized by interconnecting voltage-source three-level converters equally sharing the motor current. Drives rated for tens of Megawatts are increasingly needed as torque helpers for gas turbines in the Oil & Gas industry and one envisions that they will replace them completely in the fut...

Since the conventional electro-mechanical converter of 2D valve had problems of step lose due to its small tooth-pitch angle, a novel rotary electromagnet with large tooth-pitch angle and coreless rotor structure was proposed. Combined with the approaches of magnetic circuit analysis, finite element simulation and experimental study, the static and dynamic characteristics of electromagnet inclu...

The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were pr...

This paper presents the modelling and control of switched reluctance motor (SRM) for hybrid electric vehicle (HEV) application. Nonlinear characteristics of SRM are obtained using finite element analysis. The fuzzy logic controller is used to minimize the torque ripple which improves the average torque capability of SRM. Obtained results from the drive using fuzzy logic controller are compared ...

In this study an Adaptive Neuro Fuzzy Inference System is introduced to select the switching states of Matrix Converters. Matrix converters have received more attention in research and industrial application due its advantages like four quadrant operation, sinusoidal input and output waveforms, controllable displacement factor, less number of switches etc., Matrix Converters are efficient in sp...

Matrix Converters are becoming popular in industrial applications due its better performance than the conventional VSI converters. The advantages of Matrix Converters are bidirectional current flow, adjustable displacement angle and sinusoidal input current and output voltage. Two control schemes used to control the speed of Induction motor. They are Field Oriented Control and Direct Torque Con...
