DIRECT TORQUE CONTROL METHOD USING FUZZY LOGIC FOR IM DRIVES

Abstract

Fuzzy logic is recently getting increasing emphasis in soft computing applications in the recent days Development of high-performance control strategies for AC motor drives resulted in a rapid evolution. Today DTC uses hexagon flux path only when full voltage is required at high speeds. A novel approach of the fuzzy logic scheme for direct torque fuzzy control (DTFC) of an Induction Motor (IM) AC drive is the recent area of research. A novel approach in which DTFC is based on fuzzy logic technique switching table is described and compared with conventional direct torque control (DTC). To improve the performance of conventional DTC, modern resources of artificial intelligence like neural networks, fuzzy logic and genetic algorithms are implemented
