Compared to the proportional-integral strategy, repetitive control strategy possesses high suppression ability for alternating current (AC) harmonics of signals. Thus, RC controllers are widely used in closed-loop systems suppress periodic harmonics. In order further improve brushless DC (BLDC) motor operation performance, a frequency adaptive controller (FARC) is proposed, and then novel loop ...

In this study, real-time application and simulation of the load cell-based Segway was carried out by using an STM32F103 microcontroller. The Brushless Direct Current Motor (BLDC) current speed information recorded on SD card simultaneously during vehicle. BLDC parameters required for were entered into block diagram created in Matlab/Simulink interface. Then simulated. As a result simulation, de...

The turn-to-turn short is one major fault of the motor faults of BLDC motors and can appear frequently. When the fault happens, the motor can be operated without breakdown, but it is necessary to maintain the motor for continuous working. In past research, several methods have been applied to detect winding faults. The representative approaches have been focusing on current signals, which can g...

Multiple sensor data fusion is necessary for effective condition monitoring as the electric machines operate in a wide range of diverse operations. This study investigates acquired vibration and current signals to establish reliable multi-fault diagnosis framework brushless DC (BLDC) motor. Faults stator rotor were created deliberately by shorting two adjacent windings creating hole on surface,...

The smoothness of variable speed drive operation is critical and a viable measure used in the design and development of motion control applications. The torque produced in a brushless DC (BLDC) motor with trapezoidal back electromotive force (BEMF) is constant under ideal conditions. However, in practice, torque ripple appears on the delivered output torque. Some of these ripples result from th...
