A method of controlling a dual-wound synchronous machine includes: determining positive and negative virtual half-motor current commands based on first and a second motor current commands associated with the first and second winding sets; calculating positive and negative final voltage commands based on the virtual half-motor current commands, and using first and second sets of gain factors; and commanding, based on the final voltage commands, inverters to apply an output voltage to each of two winding sets and thereby causing output currents to be generated herein. The output currents each have a d- and q-axis components, and at least one of the first set of gain factors and the second set of gain factors is configured to cause the d-axis component and the q-axis component of the first output current to be decoupled from variations of d-axis and q-axis components of the second output current.
