| Abstract |
Modified combined direct torque control (DTC) and field oriented control (FOC) based method is proposed in this paper
to improve the performance of induction motor (IM) drive. The proposed method includes combined advantages of DTC
and FOC schemes. An algorithm is developed for closed-loop control of the proposed control method and the scheme is implemented in space vector controlled five-level diode-clamped inverter. For this, an experimental prototype is developed to control three-phase, 3-hp IM drive. The comparative performance of proposed control method, DTC and FOC with experimental results in SVM controlled five-level inverter is presented to validate the effectiveness of the proposed control scheme. Also, the switching states are selected so as to control the inverter output voltage as well as reduce the
common mode voltage (CMV) of the drive. |
