| Abstract |
Induction motor speed sensorless control, allowing operation at low and zero speed, optimizing torque
response and efficiency, is proposed. The magnitude and orientation angle of the rotor flux of the
induction motor are determined by the output of the closed-loop rotor flux observer based on the
extended electromotive force of machine. A smooth transition into the field weakening region and the
full utilization of the inverter current and voltage capability are thus made possible. The produced
torque is a continuous output variable of control. The reference tracking performance is demonstrated
by simulations and experiments. |
