Abstract :
A 30 kW induction motor drive system based on the field oriented control principle is described. The results of experiments comparing two different flux tracking algorithms are presented. In particular, a hybrid flux tracking/rotor resistance identification method is described which is applicable in situations where a fast rotor resistance identification is required. This is the case where a long idle period (when the lack of rotor current makes identification without transducers mounted on the motor possible) is followed by a demand for torque.<>
