Detection And Identification Of The Motor Parameters

This paper mainly investigated the motor's parameter identification considering the skin effect in a starting period. The motor's parameter identification plays an important role in motor control. It is both a theoretic and a practical project. After analyzing several identification methods, the writer put forward a method based on T-model equivalent circuit. To consider the skin effect, the writer modified the T-model equivalent circuit, adding the skin effect coefficients.This paper first introduced the background of this project, then emphasized on how to modify the T-model equivalent circuit. This paper also discussed the hardware and software design. In the end, the paper dealt with anti-jamming techniques.Because this is an identification in a no-load full voltage starting mode, so there are some estimations which can bring some errors. So the following work should emphasis on how to get more exact parameters. And we can also expand this project not only identify the motor's parameters but also its other characteristic.
