Abstract

This paper presents simulation results of an induction motor-fed PWM current source inverter (CSI), control system. This system has an estimator whose principal function is to perform contemporary calculations of rotor flux magnitude and induction machine load angle. The assumption made was that the estimator would be realized with the aid of a 16-bit microprocessor. Machine rotor flux observation error was checked at static and dynamic states of the entire drive system, taking into consideration: the changes in stator and rotor resistances; the stator current frequency; and various estimator sampling periods
