Position control of Two-Phase Induction motor using dSpace environment

This paper deals with position vector control of Two-Phase Induction Machine (TPIM). Indirect Rotor-Field-Oriented Control - IRFOC was used as a vector control scheme. Each phase of induction motor is fed independently by single-phase full-bridge inverter. A general model of control system of the two-phase induction machine including a position loop is proposed in the paper. The virtual high frequency injection method for position estimation without using sensor of the position is also proposed in the paper. A computer simulation and experimental verification of the position vector control of two-phase induction motor drive is realized and results are presented.
