All recommendation is summarized schematically in the following ideas:• To design a fuzzy controller that will enhance better performance. This fuzzy controllers should take into consideration the following ideas:1.
To design completely an automatic adaptive controller.2. The controller must be used to any electrical motor.3. To minimize the electrical noises, which appear in any power drive.• Design the torque ripple reduction with fuzzy logic with duty ratio controllers and also with multilevel converters.
• Design fuzzy logic with duty ratio DTC without sensor implementation that will be sensing two currents, the DC voltage and by means of observers.• Design and apply different fuzzy logic, not only to induction motors as it has been done in the present work, but also to any electrical motor
