In order to illustrate the criteria relating to static and dynamic performance, complexity of design, implementation and decoupling, a comparison was made between two asynchronous machine control techniques which are the direct torque control under the base of the SVM (DTC-SVM) and the predictive torque control (MPDTC). The results show the merits of these two control strategies with respect to the variations of the load setpoint for the torque and its influence on the speed and were obtained using a simulation program under the environment Matlab / Simulink

This paper presents the contribution of a fuzzy controller to compensate the influence of stator resistance variation which can degrade the performance and stability of a direct torque control (DTC). Nevertheless, the original term DTC refers to a strategy that provides good performance, but it also has some negative aspects to the level of switching and inaccuracy in the engine model which recommends the use of a new technique the SVM which proposes an algorithm based on the modulation of the space vector in order to carry out a predictive regulation of the torque and flux of the induction motor and provides a fixed switching frequency, thus improving the dynamic response and the static behavior of the DTC.
