The Powertrain Dynamics Library (PTDynamics) has been developed using a new approach to modelling the mechanics of rotating MultiBody systems. This paper will highlight the recent developments within the PTDynamics library with a focus on the dynamic torque converter and wet clutch models that enable the prediction of the launch feel of automatic and dual clutch transmission equipped vehicles. ...

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...

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 ...

Tradeo s between low feedgas emissions and smooth brake torque are discussed in the context of an engine equipped with variable camshaft timing VCT The use of VCT lowers the generation of feedgas emissions but adversely a ects the torque response However with the addition of an electronic throttle and knowledge of online torque the tradeo s between emissions and drivability in the VCT engine ca...

background: mechanical torque limiting devices (mtlds) are necessary tools to control a peak torque and achieving target values of screw component of dental implants. due to probable effect of autoclaving and number of use on the accuracy of these devices, this study aimed to evaluate the effect of sterilization and number of use on the accuracy of friction-style mechanical torque limiting devi...

This paper presents a design of pitch controller using Genetic Algorithm (GA) for variable speed wind turbine Doubly Fed Induction Generator (DFIG) . The proposed genetic pitch controller is used to get the proper pitch angle for limiting the mechanical power when the wind speed is greater than the rated wind speed. DFIG is a wound-rotor induction generator where the stator terminals of DFIG ar...
