The complete, lag and anticipated synchronization of a BLDCM chaotic system
Chaos, Solitons & Fractals, 2007Abstract The complete, lag and anticipated synchronizations of two identical autonomous chaotic systems, Brushless DC Motors (BLDCM) systems, are studied in this paper. PC method, linear coupling and active control are used for the achievements of the complete and the lag synchronizations.

Research on BLDCM Double Loop PWM Control Based on Positionless Sensor
Proceedings of the 4th International Conference on Computer Science and Application Engineering, 2020In order to solve the problem of positionless sensor drive control of brushless DC motors, a fuzzy PID algorithm and virtual sensors are proposed to detect the rotor position. The construction of the virtual sensor of this method is to combine the zero-crossing detection of the line back EMF and the principle of the sensor to detect the rotor position,

Analysis of skew effects on cogging torque and BEMF for BLDCM
Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 2002The variation of air gap permeance distribution is described considering the geometrical air gap. Using the air gap permeance distribution and the air gap MMF distribution, air gap flux density distribution is obtained. Equations representing cogging torque and back EMF (BEMF) are induced analytically.

Research on Sensorless Control System of BLDCM Based on TMS320F2812
Advanced Materials Research, 2012An electronic control system for sensorless BLDCM is proposed. Normally, the back-emf signal has coupling noise from the PWM signal which is used to vary the speed of the motor. So it is difficult to detect the zero-crossing point accurately when the motor work at low speed. In order to improve the controllability of BLDCM at low speed, a new algorithm

Fuzzy-PI Control for BLDCM with the Greater Inertia Load
2010 International Conference on Measuring Technology and Mechatronics Automation, 2010The big inertia torque will be produced, and the speed-adjusting system performance will become bad, when the brushless direct current motor (BLDCM) starts, speeds up and down with the greater inertia load. In order to solve this kind of problem, a fuzzy-PI control scheme combined fuzzy logic strategy and traditional PI control method was presented in ...

Simulation model for a seven-phase BLDCM drive system
SPIE Proceedings, 2007BLDC motors have many advantages over brushed DC motors and induction motors. So, BLDC motors extend their application to many industrial fields. In this paper, the digital simulation and modeling of a 7-phase brushless DC motor have been presented. The 14-switch inverter and a 7-phase brushless DC motor drive system are simulated using hysteresis ...

Hardware-in-loop simulation of wind turbine based on BLDCM
2009 World Non-Grid-Connected Wind Power and Energy Conference, 2009In order to research wind turbine (WT) power generation in laboratory conditions, which do not have wind field environment, the power generation has to be imitated. This paper analyzes the operation principle of the WT, model the torque characteristics of WT by controlling the armature current of Blushless DC Motor (BLDCM).

High Precision BLDCM Servo Control with Nonlinear Identification
2011Nonlinear factors cause great influence to brushless DC motor (BLDCM) servo control system. One common result is that servo system can not respond rapidly when the direction of reference signal changes which is a serious problem to high speed aircraft.
