Improved rotor flux observer for sensorless control of PMSM with adaptive harmonic elimination and phase compensation

Improved rotor flux observer for sensorless control of PMSM with adaptive harmonic elimination and phase compensation

In this paper, a sensorless control strategy of a permanent magnet synchronous machine (PMSM) based on an improved rotor flux observer (IFO) is proposed. Due to the unknown integral initial value and the high harmonics caused by current sampling and inverter nonlinearities, the flux linkage estimate...
