Abstract

This paper presents an auto-tuning method for the indirect vector controlled induction motor drives for the start up. The tuning algorithm is based on the rotor flux behavior of the induction motor for a stepwise torque command. An effect of the stator core loss of the induction motor, which appears in the transient motor terminal voltage caused by the undesirable rotor flux variation, is taken into account when the tuning is implemented. This method can tune the accurate inverse of the rotor time constant. Simulation results of the laboratory model system verify the validity of the proposed auto-tuning method
