SIMULATION AND SPEED CONTROL OF INDUCTION MOTOR DRIVES
... drive. In electrical drives, use of various sensors and control
algorithms is done to control the speed of the motor using suitable speed control methods.
The basic block diagram of an electrical ... dc motors were employed for drives requiring variable speeds due to ease of
their speed control methods. The conventional methods of speed control of an induction
motor were...
