Direct Torque Control of Double Feed Induction Machine (DTC-DFIM)

Abstract

This paper presents a performances study of a Direct Torque and Flux Control (DTC) for a double feed Induction Machine (DFIM). This method has become one of the high performance control strategies for AC machine to provide a very fast torque and flux control. The performance of DTC strongly depends on the quality of the estimated actual stator flux and torque. The simulation results show the effectiveness and the robustness of the proposed method in both dynamic and steady state response.
