Hind, D. M., Sumner, M., & Gerada, C. (2015). Estimating current derivatives for sensorless motor drive applications.
The PWM current derivative technique for sensorless control of AC machines requires current derivative measurements under certain PWM vectors. This is often not possible under narrow PWM vectors due to high frequency (HF) oscillations which affect th... Read More about Estimating current derivatives for sensorless motor drive applications.
