This strategy (DTC) is a very reliable solution to the problems of robustness and dynamics encountered in the other commands. The insertion of a speed sensor in applications at variable speeds made it possible to make the installation more expensive, and the possibility of losing its measurement accuracy . For this, we proposed to integrate a speed estimator based on the simplified kalman filterfrInduction motor, Direct torque control, simplified kalman filter.Thesis
