Current control of unbalanced electrical systems

IEEE Transactions on Industrial Electronics, 2001
The vector modeling approach is employed to describe the behavior of unbalanced three-phase (three-wire), unbalanced two-phase and single-phase systems. In the case of single-phase systems, a fictitious circuit is introduced in order to create the vector model.

CHAOS CONTROL BY ELECTRIC CURRENT IN AN ENZYMATIC REACTION

International Journal of Neural Systems, 1996
We apply the continuous delayed feedback method of Pyragas to control chaos in the enzymatic Peroxidase-Oxidase (PO) reaction, using the electric current as the control parameter. At each data point in the time series, a time delayed feedback function applies a small amplitude perturbation to inert platinum electrodes, which causes redox processes on ...

Robust currents control in the electric drive

2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017
The control systems of modern electric drives are built with using the principle of subordinate control, therefore the quality and accuracy of control of all external loops largely depends on internal control loops. In the article a typical, which is widely used in practice, and robust current control systems, which is obtained based on of a general ...

Safe control of palmoplantar hyperhidrosis with direct electrical current

International Journal of Dermatology, 2002
AbstractBackground Primary (idiopathic) hyperhidrosis is a benign disease of unknown etiology, leading to the disruption of professional and social life and emotional problems. A variety of treatment methods have been used to control or reduce the profuse sweating.

Electric arc current control for an electric arc furnace based on fuzzy logic

2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics, 2015
This paper presents a current control for a three-phase electric arc furnace. In order to do this, a model of the electric arc was used. Using this model, the waveforms for the arc current, arc voltage and voltage-current characteristic of the electric arc were illustrated for different arc lengths.

A controlled current inverter for an electric vehicle.

1993
The University of 'Canterbury Mark II' electric vehicle has been out of service for several years due to the lack of a suitable inverter to provide a variable frequency AC supply to its traction motors. This thesis describes the design and construction of such an inverter, using high current bipolar junction transistors as the switching elements, so ...
