To get a better electromagnetic performance of an axial flux permanent magnet brushless DC motor (AFPMBLDC), AFPMBLDC with arc-shaped magnets and its multi-objective optimization design are researched. Firstly, the main parameters proposed, initial designs carried out according to given requirements. Furthermore, pole arc coefficient, thickness, radius, air-gap length selected as factors. Then,...

This paper presents a new synchronization algorithm for grid connection of a doubly fed induction generator (DFIG) in a variable speed wind generation system. Stator flux-oriented vector control for backto-back PWM converters in the DFIG rotor circuit is used for synchronization process. By controlling the rotor d-axis current, the magnitude of the stator EMF is adjusted to be equal to the grid...

The paper has developed an optimization procedure to design the rotor lamination and magnetic sizes. average torque is improved by changing thickness of outer bridge width. Various metamodels with best prediction performance generated for each multi-objective functions constraints have been selected. By applying a genetic algorithm, several optimal solutions be considered compare those initial ...

Abstract—The aim of the paper is to design a control strategy of the BLDC motor used in EPS system is proposed, then a simulation model of control system using in BLDC motor. In the developed model of BLDC motor, the characteristics of the speed, torque, back EMF, voltages as well as currents are effectively monitored and analysed which serve a design method for a further research of BLDC motor...

Modern software development processes often use domainspecific modeling languages (DSMLs) combined with custom code generators and/or interpreters. Especially textual DSMLs as provided by Eclipse Xtext are becoming more and more popular. As a consequence, software quality assurance frequently leads back to quality assurance of the involved textual models. Here, various quality aspects have to b...

This paper presents the speed regulation scheme of a small brushless dc motor (BLDC motor) with trapezoidal back-emf consideration. The proposed control strategy uses the proportional controller in which the proportional gain, kp, is appropriately adjusted by using genetic algorithms. As a result, the proportional control can perform well in order to compensate the BLDC motor with load disturba...
