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.

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.

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.

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 ...

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 ...

Speed sensorless field orientation control of the induction machine

Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 1993
A speed estimation method for an induction machine and its application to a flux observer-based field orientation (FOFO) control system proposed previously is presented. The motor speed is estimated on the basis of the difference between two flux estimators. The convergence of the method is analyzed, and a novel pole assignment method is proposed.

Parameter sensitivity of indirect universal field oriented controllers

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 1994
The universal field-oriented (UFO) controller was developed to decouple flux and torque in an arbitrary synchronous flux reference frame, realizing a high degree of generality which makes the UFO controller compatible with all existing field-oriented controllers, including indirect and direct field orientation.

Dynamics in Vector Control and Field Orientation

2018
In Chap. 17 of Part III, vector control and field orientation have already been presented. However, the dynamics have not been analysed. In this chapter we discuss vector control and field orientation more thoroughly, including an analysis of their dynamic behaviour.
