Abstract :
The paper deals with an indirect feedforward rotor flux oriented induction motor drive in which speed estimation is performed utilising a rotor flux based MRAC scheme. A study is conducted in order to show the impact of parameter variations on main flux saturation. An attempt is made to improve the accuracy of the speed estimation by appropriate modification of the speed estimator and the indirect vector controller structures, using modified induction motor models. Excellent compensation capability is demonstrated by performing extensive simulation studies
