Nonlinear feedforward control of brushless DC motors (BLDCM)

Proceedings of the IEEE International Symposium on Industrial Electronics, 2002
In this paper, we propose a new feedforward control scheme for the control of brushless DC motors. We adopt a novel disturbance torque suppressor to eliminate the effects of the disturbance torque, uncertain inertia moment, and nonlinear friction, so that the new controller makes the velocity error to be zero at any state even when the moment of ...

Sliding mode observer for position and speed estimations in brushless DC motor (BLDCM)

2004 IEEE International Conference on Industrial Technology, 2004. IEEE ICIT '04., 2005
Back electromotive force EMF is the only electric quantity able to provide instantaneous information on the mechanical variables of the electrical motor; that is true for the position and speed. In this paper, a new sliding mode observer of the trapezoidal back EMF is applied to the BLDCM in order to ensure the control without speed and position ...

Harmonics and torque ripple reduction of Brushless DC motor (BLDCM) using Cascaded H-Bridge multilevel inverter

2013 International Conference on Power, Energy and Control (ICPEC), 2013
Brushless DC motors are widely used in variable speed drive application. The torque produced by the Brushless DC (BLDC) motors with trapezoidal back Electromotive force (BEMF) is constant under ideal condition. However in practice the torque ripple appears on the delivered output torque.

Analysis of the commutation torque ripple effect for BLDCM fed by HCRPWM-VSI (brushless DC motors)

[Proceedings] APEC '92 Seventh Annual Applied Power Electronics Conference and Exposition, 2003
The authors present an analytical study of the torque ripple due to the phase commutation in a BLDCM (brushless DC motor) fed by HCRPWM-VSI (hysteresis current regulated pulse width modulation voltage source inverter). In order to show the duration of the phase commutation and the torque ripple during the phase commutation, the instantaneous ...
