A comprehensive dynamic modelling approach to evaluate efficiency and power losses in induction motor drive systems during both transient and steady-state working conditions is proposed in this paper. The developed dynamic model considers all the main loss contributions arising both from the power converter and the motor and permits the drive efficiency to be analysed, even separating each power loss...
This paper proposes a non-linear observer for Induction Machine (IM) drives which takes into consideration the saturation effects. The non-linear observer is based on an original formulation of the dynamic model of the IM taking into consideration the magnetic saturation of the iron core. A Lyapunov based convergence analysis is proposed in order to suitably compute the observer gain guaranteeing...
This paper presents a input-output Feedback Linearization (FL) control technique for rotating Induction Motors (IM), which takes into consideration the magnetic saturation of the iron core. Starting from a new formulation of the IM dynamic model, taking into consideration the magnetic saturation, expressed in a space-state form in the rotor flux oriented reference frame, the corresponding FL technique...
