摘要： A method of controlling a permanent magnet synchronous electric machine (PMSM) drive using a Deadbeat Predictive Current Control (DBPCC) scheme is provided. The method comprises: determining d-axis and q-axis stator current values (id, iq) representative of a measured PMSM current; determining d-axis and q-axis reference current values (id*, iq*); based on the stator current values (id, iq) and the reference current values (id*, iq*), determining d-axis and q-axis current correction values (Cd, Cq); determining corrected reference current values (id**, iq**) as a sum of the reference current values (id*, iq*) and the current correction values (Cd, Cq); and controlling the PMSM drive using the corrected reference current values (id**, iq**) as reference current inputs of the DBPCC scheme. A controller for performing the method; a system comprising the controller, a PMSM and associated power electronics; and a computer program for performing the method are also provided.
