RESUMO:

This dissertation performs a theoretical review of the activation of induction machines through direct lack of control

 with direct and indirect guidance. Then it introduces the concept of predictive control and doFCS (Finite Control Set).

 PTC (Predictive Torque Control) and a robust control method, based on a beat controller, applying the concepts of

 Finite Control Set to eliminate the need for output modulators in the driver, are also analyzed.

 by controller sampling time. This strategy emulates increasing the driver sampling frequency without causing 

much impact on the computational cost of the implementation. The results present an excellent dynamic response 

for predictive methods with CFS, in addition to presenting a minimal steady state error. Furthermore, the results 

of the application of three vectors in the FCS calculation reduced the current distortion and half the torque when paid

 in PTC, going from about 9% to 5% for the current THD. The robust controller maintained its stable performance

 when there was a poor estimation of of the machine, proving to be superior to the variations inherent to the

 estimation of parameters and variation due to the temperature of the machine.
