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

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.

Field-oriented controlled induction generator with loss minimization

IEEE Transactions on Industrial Electronics, 2002
In this paper, a strategy to control an induction generator (IG) working with variable speed and load is presented and discussed. An inverter and a field-oriented controller are used in order to excite the induction machine (IM) efficiently, minimizing copper and iron losses, and to regulate the generated voltage.

Referent control of the orientation of posture and movement in the gravitational field

Experimental Brain Research, 2017
This study addresses the question of how posture and movement are oriented with respect to the direction of gravity. It is suggested that neural control levels coordinate spatial thresholds at which multiple muscles begin to be activated to specify a referent body orientation (RO) at which muscle activity is minimized.

A mean-field control-oriented approach to particle filtering

Proceedings of the 2011 American Control Conference, 2011
A new formulation of the particle filter for nonlinear filtering is presented, based on concepts from optimal control, and from the mean-field game theory framework of Huang et. al. [8]. The optimal control is chosen so that the posterior distribution of a particle matches as closely as possible the posterior distribution of the true state, given the ...

Controllable Dendritic Crystal Simulation Using Orientation Field

Computer Graphics Forum, 2018
AbstractReal world dendritic growths show charming structures by their exquisite balance between the symmetry and randomness in the crystal formation. Other than the variety in the natural crystals, richer visual appearance of crystals can benefit from artificially controlling of the crystal growth on its growing directions and shapes.

Sensorless adaptive field oriented control of brushless motor

2016 European Control Conference (ECC), 2016
“Field Oriented Control” (FOC) is the the most efficient way to control a bruchless motor. This control generates constantly a magnetic field perpendicular to the rotor, which maximises its efficiency. However, to do so, it requires knowledge of the rotor position in real time.

An improved indirect field-oriented controller for the induction motor

IEEE Transactions on Control Systems Technology, 2003
In this paper, the standard indirect field-oriented controller (IFOC) commonly used in current-fed induction motor drives is modified to achieve global exponential rotor velocity/rotor flux tracking. The modifications to the IFOC scheme, which involve the injection of nonlinear terms into the current control input and the so-called desired rotor flux ...

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.

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.
