Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model (1103.2923v1)
Published 15 Mar 2011 in math.OC, cs.SY, and physics.ins-det
Abstract: We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of fast-varying pulsating voltages and measurements of the resulting current ripples then permit to identify the magnetic parameters by linear least squares. Experimental results on a surface-mounted PMSM and an interoir magnet PMSM illustrate the relevance of the approach.
