Abstract: In this paper, the authors present an original control law for induction motor drive. It is based on a dynamic reconfiguration of a basic direct torque control (DTC) algorithm and a direct torque control algorithm associated to space vector modulation (SVM-DTC). The criterion of reconfiguration concerns the state of the machine. Indeed, during transient states DTC algorithm is activated in order to get the best torque dynamic. Then, at steady-state, a SVM-DTC algorithm is preferred because it allows to reduce significantly the torque ripples. Besides, an original and well-adapted modelling based on a polar representation of the state variables is also introduce. Finally, experimental results are presented that confirm the interest of this solution.
