Field-oriented control of an induction machine with winding asymmetries

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
Modern electrical AC drives with best available performances are based on the so-called fundamental wave machine model approaches. This paper introduces an upgrade of fundamental wave model approach by respecting both inherent and fault-induced deviations of machine flux from its fundamental component.

Field-oriented control induction machine and control by sliding mode

Simulation Modelling Practice and Theory, 1997
Abstract This paper deals with the implementation of an “optimal” field oriented control on an induction machine. In a first step, an optimal control law is applied, which minimizes the time, to establish the required flux for a field oriented control.

The universal field oriented controller

IEEE Transactions on Industry Applications, 1994
This paper synthesizes and develops a universal field oriented (UFO) controller for induction machines. The UFO controller decouples flux and torque in an arbitrary flux reference frame. Due to its high degree of generality the UFO controller lends itself to be fully compatible with all existing field oriented controllers, indirect as well as direct ...

Indirect Field Oriented Control for Induction Motor

2011 Fourth International Conference on Emerging Trends in Engineering & Technology, 2011
Indirect Field Oriented Control (IFOC) is known to produce high performance in induction Motor (IM) drives by decoupling rotor flux and torque producing current components of stator current. The decoupling control between the rotor flux and the torque is no longer achieved in terms of stator current components this paper introduces a decoupled rotor ...

SERVICE-ORIENTED ARCHITECTURE FOR FIELD CONTROL DEVICES

IFAC Proceedings Volumes, 2006
Abstract The concept of Service-Oriented Architecture has become more and more important in the last few years in several technological fields and is beginning to play an important role also in the industrial automation field. The paper presents the application of this paradigm to field control devices of a flexible manufacturing system.

Fuzzy supervisory control of field oriented controlled AC drives

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
The problem of setting an optimum flux reference for indirect vector controlled induction motors is addressed. The flux reference is generated using a fuzzy logic supervisor (FLS) which minimizes the power input to the motor in steady-state speed operations. The FLS is based on a simple search method.
