Abstract :
The paper deals with real-time estimation of PMSM rotor position, which is based on the new, virtual HF injection signal method. The main idea of that is subtraction of virtual injection voltage from real stator voltage. This voltage is acting on PMSM model and causes a virtual current response. After subtraction of acting model current from measured real stator current we obtain the virtual HF injection current signal, suitable for filtering and extracting of rotor position. On the end of the paper the simulation results of rotor position determination are given
