Direct torque neuro-fuzzy control of induction motor drive. DSP implementation

This paper presents the DSP implementation of a new induction motor drive control strategy of discrete direct torque control based on a neuro-fuzzy structure. These control strategies guarantees very good dynamic and steady-state characteristics with low sampling time and constant switching frequency. The laboratory control unit and DSP calculation scheme are presented. The practical and simulation results of direct torque neuro-fuzzy control are compared and show very good agreement.
