Optimal Control for Single-Phase Brushless DC Motor with Hall Sensor

This study deals with the optimization control of a single-phase brushless DC motor (BLDCM) with Hall sensor. A simple modeling method with feasible parameter identification is adopted to meet characteristics of singlephase BLDCM. With the linear Hall sensor feedback, the advantages of current-mode control scheme and softcommutation scheme are proposed to achieve maximum efficiency over the ent...

Torque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

Atmel AVR443: Sensor-based Control of Three Phase Brushless DC Motor

In a Universal DC motor, brushes control the commutation by physically connecting the coils at the correct moment. In BLDC motors the commutation is controlled by electronics. The electronics can either have position sensor inputs that provide information about when to commutate or use the Back Electromotive Force generated in the coils. Position sensors are most often used in applications wher...

Simulation of MRAC based speed control of brushless DC motor with low-resolution hall-effect sensors

A novel speed estimation approach with control system based on model reference adaptive control (MRAC) is presented for low cost brushless dc motor drives with low-resolution hall sensors. The back EMF is usually used to estimate speed. But the estimation result is not accurate enough at low speeds because of the divided voltage of stator resistors and too small back EMF. Moreover, the stator r...
