Abstract

This paper aims to the identification of a Permanent Magnet Synchronous Machine parameters by using Diffedge approach. In this case, the identification problem is considered as an optimization one. Parameters sensibility, the exact calculation of gradient and Jacobean in respect with the parameters are done by using symbolic derivative expressed by diagram. Two optimization process are here proposed: the first method uses the formal Jacobean found by finite differences and the second one uses the formal Jacobean calculated by Diffedge. The proposal validation consists of the convergence comparison and obtained results. It is here highlighted that the Diffedge approach leads to better results as convergence, robustness.
