Abstract
A control method implemented in a power converter including an inverter connected to a synchronous electric motor including permanent magnets, the electric motor being modeled in the power converter by a mathematical model of currents in the electric motor expressing a flux current and a torque current on the basis of magnetic-saturation parameters. The control method identifies magnetic-saturation parameters during a learning procedure including applying a static voltage signal and a high-frequency voltage signal along an axis of the flux and/or an axis of the torque of the motor to cause an oscillation of the current on the axis of the flux and/or on the axis of the torque.
