Parameter identification of PMSM

The following paper describes an identification of quadrature inductances of a permanent magnet synchronous motor. This identification is a frequency analysis base on an injection of a harmonic signal to control. This method utilizes knowledge of synchronous motor schema in d-q coordinates and it is based on mutual signals correlation. This method is primary an offline method. But in this paper it is used as an online method. The algorithm was tested on a real motor through a real time platform D-space.
