Perancangan dan Pengujian Sistem Pengendali Sudut untuk Motor DC Brushless Menggunakan Kendali Algoritma P-D

open access: yesJurnal Rekayasa Elektrika, 2017
Many industrial applications use servo motor because of its accuracy and user-friendly, but by using it in an application, a higher cost is required.  To make an actuator with good precision and universal purpose but with lower cost, a position control ...

Optimization of PM brushless DC motor drive

open access: yesIEEE International Conference on Industrial Technology, 2003, 2004
Traditional approaches to controller designs that guarantee fast compensation of load torque and reference variations result in design iterations and most of the time in poorer response for load torque variations. In this paper a reference model f or desired drive behavior generation and optimization methods has been applied to achieve controller ...

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 40, Issue 4, Page 890-903, April 2026.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Closed-loop correction strategy for commutation deviation of BLDC motor based on internal power factor angle detection

open access: yesEnergy Reports, 2023
The first-order inertia of the armature winding of the brushless DC motor will cause current offset, which will reduce the electromagnetic torque. In the sensorless drive of brushless DC motors, correction of commutation point is an effective solution to
