Abstract

This paper describes method of synchronous motor parameter identification. This is improved frequency analysis (IFA). This method is mainly used for off-line identification parameter and is very resistant to noise. Because it is useful for this identification we use this method for on-line identification parameter. But this method has several disadvantages. One of then is dependence on controller settings. The following article describes on-line method and its changes.
