خلاصه مقاله:

In this paper the induction motor’s parameters and speed are estimated by the application of two methods. The Extended Kalman Filter (EKF) and Recursive Least Square (RLS) are used to implement the estimator. Combination of these algorithms has been investigated and the results are presented. The possibility of the application of these methods for on-line motor speed and parameter estimation for using in drive application has been analyzed. The theoretical development of algorithm is followed by simulation study which is used to illustrate the possible range of behavior including the introduction of noise and modeling errors.
