Abstract
In this paper a novel high-performance direct power control (DPC) approach for induction motor (IM) drive is presented. The majority of the high performance drives employ induction machine due to its several advantages and hence it necessitates precise control over a wide range of speed with better power factor. In the conventional direct torque control (DTC) and field oriented control (FOC), where flux and torque estimation is required, the DPC consists of controlling the real and reactive power flowing in and out of the IM and remarkably improves the power factor. The DPC significantly recovers the certain disadvantages of conventional control schemes without integration of complex observers, filters, and reactive power compensators. Therefore, in this paper simulation studies are carried out and results are compared with the conventional indirect rotor FOC scheme to validate the proposed control scheme.
