Compared with the position sensor control, sensorless control avoids a lot of defects caused by the position sensor, at the same time makes the system more stability and stronger anti-interference performance, it has more advantages and meets control field's requirements better in the future, it has gradually become a hotspot in the brushless DC motor control field. The rotor position detection has...
Aim at the starting problem of the sensorless brushless DC motor, sensorless brushless DC motor based on the Matlab/Simulink studies the startup process, and puts forward an optimization scheme. According to the motor stator core saturation effects, with simultaneous input of 6 short-time pulse detection method of rotor position, and then determine the phase sequence to be driven, applied to the motor...
