The direct torque control (DTC) of an induction motor (IM) has been the subject of several studies and developments since the eighties. Efforts have been made continuously to improve the performance of this control technique to make it more efficient and robust for industrial applications that have also experienced a remarkable development. It cites, among these applications, the tracking system, which was the subject of much research. This study provides experimental validation of the algorithms developed in this topic, and help for implementation of a simple DTC, to apply it to the tracking system, proposed by the authors. The interest of this study is that it is based on the choice of switching tables (ST) and therefore on algorithms and not on the hardware part, which is expensive. The tests were carried out under the same conditions with the same equipment of the testbed, to get a good comparative study. Three variants were tested: simple ST, table of sectors shifted by 30 ° and a table with 12 sectors. The results show an improvement, but a dilemma between the torque ripple and those of the stator flux
