Abstract :
This paper presents a simple technique based on stator flux estimation to control the electromagnetic torque of induction motors during soft starting. The inherent problems related to pure integration of the back electromagnetic force to estimate the stator flux are minimized using the low pass filter approach. The experimental results are dealt with and compared to the usual current control technique.
