Bifurcation Control and Complex Dynamics in Field-Oriented Control of a PMSM

Journal of Circuits, Systems and Computers, 2019
The 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, 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.

Comparing the indirect field-oriented-control with a scalar method

Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 1994
Two 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 Synchronous Machines

IETE Journal of Research, 1991
Although 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.

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

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.

A neural network controller for indirect field orientation control

IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002
This paper presents the design of a neural network controller for the stator current command in an indirect field oriented system. A particular three layer neural network structure is studied in some detail. This neural network controller has two outputs, stationary frame q and d axis current commands i/sub qs//sup s/ and i/sub ds//sup s/. The input to

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 ...

Field-Oriented Vector Control of Synchronous Motors With Additional Field Winding

IEEE Transactions on Energy Conversion, 2004
Summary form only given. This work presents a new method to control a synchronous motor in such a way to resemble the characteristics of a DC motor. The method suggests including a second field winding to the rotor of a voltage-source-inverter-fed synchronous motor.
