Self-commissioning for vector controlled induction motors

A set of automatic tuning schemes for vector-controlled induction motors is described. The tuning approach described here is for a current control minor loop, a speed control loop, and a vector control loop. The tuning concept common to these three control loops involves using the relations between response waveforms, motor parameters, and control parameters. Experiments were performed and some typical results are presented to verify the self-commissioning schemes proposed here
