摘要

Estimation of rotor resistance rapidly and accurately has received a lot of attention due to its significance in improving the performance of induction motor(IM) vector control system. In this paper, algorithm of estimating rotor resistance of IM based on extended Kalman filter(EKF) is presented. The algorithm can estimate the rotor resistance on line by measuring the voltage, current and speed of stator. Using MATLAB/SIMULINK, a simulation model is built and tested. The simulation results show that the presented algorithm is effective and accurate.
