SERVICE-ORIENTED ARCHITECTURE FOR FIELD CONTROL DEVICES
IFAC Proceedings Volumes, 2006Abstract 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.

Indirect Field Oriented Control for Induction Motor
2011 Fourth International Conference on Emerging Trends in Engineering & Technology, 2011Indirect 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 ...

Fuzzy supervisory control of field oriented controlled AC drives
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002The 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.

Bifurcation Control and Complex Dynamics in Field-Oriented Control of a PMSM
Journal of Circuits, Systems and Computers, 2019The general purpose of this paper is to develop new aspects of bifurcation structures in a 3D parametric space. Identification of generic bifurcation structures in former studies was based on the arrangement of bifurcation curves in the parameter plane.

An alternative strategy for field oriented control
2006 American Control Conference, 2006A new control strategy based on optimal control theory is developed in this paper and applied to an induction motor drive. The distinguished feature of the proposed control design is that it achieves the same performances as the field oriented control without the need for heavy and expensive gain tuning.

Field Oriented Control of Synchronous Machines
IETE Journal of Research, 1991Although field orientation in induction machines is only 20 years old, the corresponding concept in synchronous machines dates back almost 60 years to the days of the thyratron tube. After a brief historical review, the basic theory of synchronous machine field orientation is outlined.

Comparing the indirect field-oriented-control with a scalar method
Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 1994Two methods of induction motor control are examined. The indirect field-oriented (IFO) and the slip-control (SC) methods are formally compared. Their block diagrams are derived, analyzed and their similarities shown. It is demonstrated that the difference between the two is just due to a feedforward block that computes the current phase to be supplied ...

Field oriented control of a synchronous drive
IEEE International Conference on Electric Machines and Drives, 2005., 2005Field oriented control (FOC) may be used for simple high-power synchronous drives, such as pumps and fans, to unify system with asynchronous drives. But distinction is strong influence of torque component of current on flux. Internal feedback in control object is investigated. This feedback becomes positive one in definite regimes. A simple addition in

Principles of Vector Control and Field Orientation
1996Abstract In this chapter the basic concepts of torque control and field orientation are introduced based on steady state considerations for both synchronous and induction machines. A basic set of three requirements which enable direct control of machine torque production is developed and used to illustrate the type of controller ...
