High Frequency Response Current Self-Demodulation Method for Sensorless Control of Interior Permanent Magnet Synchronous Motor

In the sensorless control, high frequency (HF) rotating sinusoidal voltage injection method requires the position error compensation algorithms to eliminate the side effect of system delay. However, the implementation complexity of the system is increased and the optimization of dynamic performance...
