A variety of control techniques, different in concept, are described, Direct Torque Control (DTC) with Space-Vector Modulation (DTC-SVM), trends in the DTC-SVM techniques based on neuro-fuzzy logic controllers and Vector control for Slip energy recovery in DFIG is presented. The increasing importance of speed or position sensorless speed and torque control techniques. Keywords: Alternating vector Control (AC);Direct Torque Control (DTC);Induction Motor (IM);Synchronous Motor (SM);Switched Reluctance Motor (SRM)
