Abstract
The Previously used conventional DTC for Induction motor speed control was robust and had good dynamic performance. Apart from this the conventional system also had certain shortfalls .These include the deviating switching frequency with hysteresis bands and also it cannot optimally decide the selection of the voltage vector . As the band limits of hysteresis controllers for torque and flux remain fixed the torque and flux ripples are high. Hence here we try to find a new and fast direct control technique with fast torque response and constant switching frequency by optimizing the selection of the voltage vectors to give maximum rate of torque increase. Keywords- Induction motor(IM) drives ,Direct Torque Control(DTC)
