Comparative study of low-pass filter and phase-locked loop type speed filters for sensorless control of AC drives

High quality speed information is one of the key issues in machine sensorless drives, which often requires proper filtering of the estimated speed. This paper comparatively studies typical low-pass filters (LPF) and phase-locked loop (PLL) type filters with respect to ramp speed reference tracking a...
