Hardware Implementation of Various DTC Strategies Using dSpace 1104 for Induction Motor Drive

Résumé

This paper presents different enhancement techniques of basic direct torque control strategy for induction motor drive. It is well-known that the conventional DTC suffers from high torque ripples and variable switching frequency due to utilizing hysteresis comparators and lookup switching table. In this paper two improved techniques are presented. The first one deal with the use of an extended switching table which divides the flux locus into twelve sectors instead of six in order to solve control ambiguity and reduce ripples. The second technique bases on replacing the switching table by space vector modulation in order to maintain a fixed switching frequency and to minimize consequently the high torque and flux ripples. The effectiveness of the presented algorithms is investigated by an experimental implementation with the aid of real-time interface (RTI) based on dSpace 1104 bored.
