【Abstract】 The sensorless of induction motor field-oriented control employing stator voltages and currents has difficulty in estimating rotor flux in the low-speed range.This paper investigates the rotor flux estimator which replace integrators with two lag circuits. The experimental results indicate good speed responses.更多还原
