This paper presents a new technique for Rotor Field-Oriented Control (RFOC) of a single-phase induction motor (IM) with two asymmetrical main and auxiliary windings. Using this technique, transformation matrices are introduced and applied to the equations of single-phase IM. It is shown that by applying these transformation matrices to the equations of singlephase IM, asymmetrical equations of RFOC for single-phase IM are transformed into symmetrical equations. These rotational transformations are derived based on a simplification to the steady state equivalent circuit of a single-phase IM. Finally, simulation results are presented to demonstrate the excellence performance of the presented method.
