This paper presents a universal flying restart strategy for scalar (V/f) controlled induction
machines. The proposed method performs a frequency search to estimate the rotor speed …

In the application of electric railway traction, induction machines may suffer momentary
power interruptions. Restarting control while machine running is a critical part of such …

The adoption of the conventional V/f control strategy for restarting a free-running induction
motor driven by a high-voltage inverter tends to cause an impact current on the stator side …

Aiming at eliminating the inrush current that brought by residual voltage, a fast, reliable and
easy implemented control strategy is proposed to restart a free-running induction machine …

Electrical variable speed drives (VSDs) are the most widely used power-electronics-based
equipment in the industry that controls the performance (speed and torque) of AC induction …
