| Abstract: | This paper presents a speed sensorless control scheme of an induction machine combining a novel fundamental-frequency current injection method in the low-speed region and the flux estimation method based on the stator voltages and currents in the high-speed region. The rotor flux position can be estimated from d-axis stator fundamental-frequency current injection and the signal processing in a low-speed region. In the high-speed region, the rotor flux position can be estimated by the rotor flux from the voltage and currents information. Experimental results based on rotor field-oriented control are given to verify the proposed scheme. |
