Improved Self-commissioning of Electrical Parameters for Vector Controlled Induction Motors

Abstract

The operating characteristics of the sensorless vector-controlled induction motors are generally affected by motor parameters. Starting from the basic concept, the paper presents the practical self-commissioning techniques of electrical motor parameters of sensorless vector-controlled induction motors. By using the proposed method, the control accuracy is improved up to ±0.5% in peed and ±5% in torque, respectively.
