Field oriented control of a synchronous drive

IEEE International Conference on Electric Machines and Drives, 2005., 2005
Field 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

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 ...

Field oriented control drives for naval mechanisms

IEEE EUROCON 2009, 2009
In this paper, the authors propose the embracing of a solution regarding the implementation of the direct vector control in torque and flux on the induction motor with squirrel cage rotor for the electrical drive systems of the naval mechanisms. Through this is desired the replacement of the actual technical solution, at which for the drive of the ...

Field oriented control of synchronous reluctance machine

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
Control strategies, practical implementation and performance issues related to field-oriented control of synchronous reluctance motors are presented. In particular, a speed invariant current controller, variable d-q current limit and variable speed loop gain are proposed.

Parameter insensitive controllers for field-oriented controlled induction machines

Proceedings of 5th International Conference on Power Electronics and Variable-Speed Drives, 1994
The paper describes practical experiences of the use of a digital sliding mode controller for control of an inverter fed induction machine. It is shown that such a controller has several advantages in comparison to a conventional PI controller. Through linearisation of the nonlinear controller, the method of pole assignment can be used. The programming

Adaptive field oriented control of induction motors

1997 European Control Conference (ECC), 1997
In systems without converters for measuring the stator voltages, only reduced order observers based on the current equations are seen. Full order rotor flux observers are not applicable because stator voltage measurements are used. This problem is in this paper managed by an adaptive approach leading to a completely new method called Field Angle ...

Principles of Vector Control and Field Orientation

1996
Abstract 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 needed ...

Dynamics of Vector Control and Field Orientation

1996
Abstract The steady state analysis in Chapter 5 has been used to demonstrate the basic concepts of vector control and field orientation in both synchronous and induction machines. The underlying motivation in Chapter 5 was to obtain torque (and flux) control independent of motor speed.

An alternative strategy for field oriented control

2006 American Control Conference, 2006
A 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.
