Abstract

A method for controlling a drive system (1) including a synchronous motor (3) having several phases comprises the steps: providing appropriate operating parameters for the synchronous motor (3) by processing input of the drive system (1); in case of a determination of a fault of one of the phases, calculating a zero sequence voltage for a neutral conductor based on motor parameters estimated by means of a parameter estimation algorithm based on detected operating parameters; and applying the calculated zero sequence voltage to the neutral conductor.
