A new Direct Torque Control for a better efficiency of the induction motor

Abstract

This document proposes an energetic output improvement of electric drives for induction motors. This modification pointing toward a better energetic output (improving the efficiency) according to the application, and can be made in the most common control algorithms as the FOC (Flux Oriented Control) and the DTC (Direct Torque Control). The increase in drive's efficiency supposes on the one hand, a considerable economic saving and, on the other hand, a reduction in the environment pollution.
