Abstract

The paper deals with speed vector-controlled induction motor drive systems, in which the rotor flux estimation is performed using Luenberger and Kalman estimators. A comparative study of the stability of the estimators and of the control systems which are included in the control loop is presented using both simplified and full discretisation method and modifying the sampling time used for each of the methods. The study is focused especially on the low and high speed regions. The conclusions are based on the comparing of the eigenvalues of the estimators in each studied case
