Abstract

This paper presents a new induction motor drive control strategy in the discrete direct torque control scheme based on a neuro-fuzzy structure. Two schemes are proposed: a neuro-fuzzy switching times calculator; and a neuro-fuzzy incremental controller with space vector modulator. These control strategies guarantee very good dynamic and steady-state characteristics, with very low sampling time and constant switching frequency. The proposed techniques are verified by a simulation study of the whole drive system and the results are compared with the conventional discrete direct torque control method
