Abstract
A method for adapting the control parameters of an electric traction machine being a permanent magnetic synchronous motor, PMSM, the method comprising providing the flux linkage of the permanent magnets, PM flux, in the PMSM; performing a stand still characterisation of the PMSM to estimate linked magnetic flux as a function of current; adding the PM flux to the estimated linked magnetic flux to provide a flux characteristic of the PMSM; adapting the control parameters of the PMSM based on the flux characteristic.
