A method of controlling a plurality of permanent magnet synchronous motors using a single inverter that includes obtaining an estimate of rotor position and speed individually for a plurality of permanent magnet synchronous motors. The method can include calculating the average rotor position from the obtained estimate of the rotor position for each permanent magnet synchronous motor of the plurality of permanent magnet synchronous motors. The method can include reconstructing a rotor permanent-magnet flux for each permanent magnet synchronous motor and transforming the reconstructed rotor permanent-magnet flux for each permanent magnet synchronous motor to average fluxes and average differential fluxes on an average d-q reference frame. The method can include obtaining the average current reference in the average d-q reference frame for the plurality of permanent magnet synchronous motors; and determining an inverter voltage reference.
