Paper Title
Implementation Of A Direct Torque Control Algorithm For Induction Motor Drives For Fast Torque Response
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.
