Abstract

For high-performance vector control of an induction machine, rotor resistance estimation is required. The commonly used state-space class of estimators requires voltage transducers as instantaneous phase voltages are used in the estimation algorithm. A phase voltage estimator is developed for a pulsewidth modulation voltage-source inverter. The voltage estimates are used in a rotor resistance estimator and practical results show that the usual phase-voltage transducers are unnecessary
