OSTI ID:1532117
Embodiments of the present disclosure relate to methods, systems and apparatus for controlling operation of an electric machine in a vector controlled motor drive system when the electric machine operates in an overmodulation region. The disclosed embodiments can reduce variations/errors in the phase voltage command signals applied to the multi-phase machine so that phase current may be properly regulated thus reducing current/torque oscillation, which can in turn improve machine efficiency and performance, as well as utilization of the DC voltage source.
