On-line parameter estimation of PMSM in open loop and closed loop

Abstract

The paper discusses the multi-models approach for on-line parameter estimation of permanent magnet synchronous motor (PMSM). The study is focused on a PMSM with non sinusoidal electromotive force (emf) in open loop and closed loop conditions. The electrical parameters of 2-phases models in Extended Park frame are estimated by using the recursive least squares algorithm (RLS).
