This paper proposes a gradual pole changing technique for field-oriented control (FOC) of pole phase modulated (PPM) induction motor drive (IMD). The PPM gives wide and flexible torque-speed ranges. However, the pole changing technique suffers with major constraint during pole changeover. The conventional pole changing technique adopts instantaneous pole changing, which causes high stator current and subsequent flux distortion during pole transition. It degrades the performance of PPM-IMD with negative torque and speed disturbances. This paper proposes, a gradual pole changing technique for a FOC of IMD to overcome the problem of instantaneous pole changing control during pole change and its impact on the system dynamics. The proposed gradual pole changing technique for FOC of PPM-IMD provides fast and accurate response both in transient and steady state operation which is the desirable quality for EV application. The proposed methodology also has greater system dynamics, which provides maximum torque during both in acceleration and deceleration periods. To validate the proposed gradual pole changing for FOC technique of PPM-IMD a designed Ansys model of 5 HP, 415V, three-phase, twelve-pole (3-ph, 12-P) induction motor drive is adopted. The model is implemented by reconfiguring the designed model to a nine-phase, four-pole (9-ph, 4-P) and results are realized in MATLAB/Simulink environment.
