Brushless Direct Current (BLDC) motors are widely used due to high reliability, simple frame, straight forward control, and low friction. BLDC motor has the advantage of high speed adjusting performance and high power density. Speaking of the motor drive control, the most important part is commutation control.

In this paper, a new adaptive reference based approach to direct torque control (DTC) method has been proposed for brushless direct current (BLDC) motor drives. Conventional DTC method uses two main reference parameters as: flux and torque. A main difference from the conventional method of it was that only one reference parameter (speed) was used to control the BLDC motor and the second control...

This study presents the simulation of brushless DC (BLDC) motor control in MATLAB/Simulink environment with model-based and direct torque (DTC) method extended kalman filter (EKF). In this study, a based on DTC is tested to nonlinear BLDC filter. method, an accurate can be made thanks load moment estimation, which not found literature. As result tests have carried out at low high speeds, it con...

In recent years, the deterministic design optimization method has been widely used to improve output performance of brushless direct current (BLDC) motors. However, it does not contribute reducing failure rate and variation products because cannot determine manufacturing uncertainty. this study, we proposed reliability-based robust torque a BLDC motor while variation. We calculated vibration re...

Brushless direct current motors (BLDC) are prominent due to their high efficiency and less maintenance. However, BLDC motor applications limited the requirement of a complex controller, existence torque ripple, cost.

In this paper, the main objective is to identify the parameters of motors, which includes a brushless direct current (BLDC) motor and an induction motor. The motor systems are dynamically formulated by the mechanical and electrical equations. The real-coded genetic algorithm (RGA) is adopted to identify all parameters of motors, and the standard genetic algorithm (SRGA) and various adaptive gen...

This study focused on the efficiency improvement and acoustic noise reduction of brushless DC (BLDC) motors by reducing current harmonics using a novel BLDC commutation method.
