Stand-Still Self-Identification of Flux Characteristics for Synchronous Reluctance Machines Using Novel Saturation Approximating Function and Multiple Linear Regression
A current-fed inverter-reluctance motor drive controlled in a closed-loop is described. A method of characterization is presented which takes the saturation into account in direct and quadrature axes. An experimental method is described which is able to determine direct and quadrature inductances with influence of the magnetomotive force (MMF) in one axis upon the flux in the other axis. The model is then used for the investigation of the electromechanical characteristics of the converter-machine system. Calculated results are compared with experimental results.
