BARRIGA TURRIAGO, Camilo  and  ZAMBRANO, Juan. Starting an induction motor with a fuzzy controller. Tecnura [online]. 2011, vol.15, n.30, pp.32-43. ISSN 0123-921X.

This paper presents the use of fuzzy logic as part of artificial intelligence in the area of power electronics and motor drivers to improve performance during the startup of an induction motor. To feed the induction motor, two circuit conthyristors connected in ant parallel and a threephase inverter. Control strategies such as soft start and Direct Torque Control incorporating fuzzy control have been current proposals to reduce and improve torque. The results of a simulated induction motor squirrel cage of 1.1 KW to these electronic methods show an improvement in performance at boot time, reducing power and increasing the torque.

Keywords : Soft start; direct torque control; three-phase inverter; fuzzy logic; induction motor; thyristor.
