Abstract :
In this paper, an online identification method of a PMSM´s (permanent magnet synchronous motor) electrical parameters based on decoupling control is proposed. Its practical implementation is very simple, especially in the case of a nonsalient pole PMSM. A global stability study based on the second method of Lyapunov guarantees the convergence of the estimated parameters under certain conditions. The simulation results as well as the experimental ones illustrate the validity of the analytic approach and the efficiency of the proposed method.
