摘 要：The purpose of this study is to illustrate a new method for sensorless vector control of induction *** approach uses Zero-Crossing Times（ZCT）signal of stator current to estimate rotor *** signal contains useful information which can be used for estimation of rotor speed and *** have used this information for online estimation of rotor *** avoid time consuming Fast Fourier Transformation（FFT）analysis of ZCT signal,we have used switchable high order Butterworth Filters in order to extract rotor *** result has expressed good performance of this simple and inexpensive sensorless vector control of induction motors.
