Real-time implementation of direct torque control using fuzzy logic and analytic approaches of an induction machine

This paper proposes two approaches for direct torque control. The first approach based on an analytic optimization of a quadratic criterion related to the transient machine behavior. The second based on fuzzy logic concept. The developed fuzzy logic controller uses mainly the input/output data. The real-time implementation is here described and the experimental and simulation results are compared. A sufficient agreement between the two results have been obtained.
