In this paper, an optimum-efficiency control scheme of synchronous reluctance motors is presented. There exists a variety of combinations of d- and q-axis current which provides a specific motor torque. The objective of the optimum-efficiency controller is to seek a combination of d- and q-axis current components, which provides minimum input power, that is, minimum losses at a certain operating point in steady state. A small amount of perturbation is added to the d-axis current reference for the purpose of searching a minimum input power operating point.
