In many Sensorless Field Oriented Control schemes for Induction Motor (IM) drives the flux is estimated by means of the measured motor currents and the control reference voltages. In most of cases, the flux estimation is based on the integral of the back-EMF voltages. The inverter nonlinear errors (dead-time and on-state voltage drops) introduce a distortion in the estimated voltage that reduce...

In this paper combination of a load-commutated inverter (LCI) and a voltage-source inverter (VSI) are employed for performance analysis of induction motor drive. Performance of the drive has been evaluated through the different variation in reference speed and load torque. proposed LCI-based induction motor drives include the following Advantages: 1) sinusoidal motor phase current and voltage b...

Controlled induction motor drives without mechanical speed sensors at the motor shaft have the attractions of low cost and high reliability. To replace the sensor, the information on the rotor speed is extracted from measured stator voltages and currents at the motor terminals. Vector controlled drives require estimating the magnitude and spatial orientation of the fundamental magnetic flux wav...
