Minimization of zero-current clamping effects in pulsating high frequency signal injection axis switching based sensorless permanent magnet motor drives
Minimization of zero-current clamping effects in pulsating high frequency signal injection axis switching based sensorless permanent magnet motor drives
The invention the position and speed sensorless estimation of the electric motor drive device using the sensor-less control scheme of the system for injecting high frequency of the pulse wave form to estimate the position and speed of the permanent magnet synchronous motor position error and velocity control Dynamic major degradation minimizing the zero-current-clamping phenomenon that causes relates to a novel sensor-less control.
