Abstract This study presents a new predictive control approach for brushless DC (BLDC) motor to smooth its commutation process. The proposed method is applied the BLDC motor's equivalent current. Therefore, this utilises only one prediction equation, which means less calculation than standard schemes. Here, current equation defined according model‐free theory remove back‐EMF voltage estimation ...

This application note describes a driver solution for single winding single-phase BLDC, based on the PIC16F1613 microcontroller. The driver exploits two feedback loops: the inner loop, which is responsible for the commutation control, and the outer loop which is responsible for the speed control. The speed of the motor is referenced to an external analog voltage. Fault detection can be sensed d...

This paper describes a simple way to control, in a sensorless way, a Brushless DC (BLDC) motor for electric vehicle applications. To control this machine it is generally required to count with a position sensor because the inverter phases, acting at any time, must be commuted depending on the rotor position. Encoders and resolvers have been used for sensing rotor position with respect to stator...

High performance applications are now days utilizing the brushless DC motor (BLDC) drives due to its ruggedness, compactness, high torque weight ratio, dynamic response etc. feature of square-wave current excitation waveforms in BLDC allows some major system simplifications for trapezoidal motors.

In classical control of brushless dc motors, flux distribution is assumed trapezoidal and fed current is controlled rectangular to obtain a desired constant torque. However, in reality this assumption may not be correct due to nonuniformity of magnetic materials and design trade-offs. These factors together with current controller limitation, can lead to an undesirable torqueripple. Hence torqu...
