Controllability analysis for current profile control in tokamaks

Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009
The control of the toroidal current density spatial profile in tokamak plasmas will be absolutely critical in future commercial-grade reactors to enable high fusion gain, noninductive sustainment of the plasma current for steady-state operation, and magnetohydrodynamic (MHD) instability-free performance.

CONTROL OF CHAOS IN CURRENT CONTROLLED DC DRIVES

Journal of Circuits, Systems and Computers, 2013
In this paper, subharmonic and chaotic behavior in current controlled DC drive has been investigated. The effects of variation of some chosen parameters on the qualitative behavior of the system have been studied. To avoid occurrence of chaos we present a method for controlling chaos applicable to DC drives.

Current Trends in Population Control

Fertility and Sterility, 1964
In the face of the constant growth of population the only hope is a reduction in the number of births. The author reviews what has been done to achieve this in terms of current efforts in Japan India and China and developments in contraceptive methodology.

Predictive Current Control Using Identification of Current Ripple

IEEE Transactions on Industrial Electronics, 2008
This paper presents a new time-discrete predictive current control for permanent-magnet synchronous motor (PMSM) which follows a reference step in two sampling periods. The control stands out by using a permanent identification which allows fast control even if the motor parameters are changing.

A new differential current- controlled current conveyor and its differential ladder current-controlled current-mode filter

2007 International Workshop on Electron Devices and Semiconductor Technology (EDST), 2007
the paper presents a new differential current - controlled second generation current conveyor circuit with multiple outputs (MO-DCCCII). The principle of the circuit is analyzed in detail. In this circuit, the voltage relations between the differential input Y and the differential terminal X can be tuned by the extra bias current and no restriction is ...

Current problems in the control of mosquitoes

Nature, 1978
Since the incidence of mosquito-borne disease was drastically reduced by the use of DDT in the 1950s, the problem has again worsened and no single method of eradication seems likely to achieve lasting success. It now seems that the best hope lies in the combination of various methods of chemical control and perhaps genetic control to rid the Third ...

Average Current Control with Symmetrical Sawtooth or Peak and Valley Current Control

2019 European Space Power Conference (ESPC), 2019
Conductance control within SMPS (Switch Mode Power Supply) for space power systems is typically implemented relying on ACC (Average Current Control). Such technique is driven by a comparison between the electrical current and a sawtooth signal being either asymmetrical or symmetrical.

The sign test in Current Control

Statistische Hefte, 1985
Current control of a continuous random variable is investigated without assuming a normal distribution. The sign test is used as test procedure. The parameters of the corresponding control chart are to be determined in such a way that in the long run the expected loss per produced item is minimal.

A current controlled CMOS current amplifier

2017 5th International Symposium on Electrical and Electronics Engineering (ISEEE), 2017
A new circuit solution for current controlled current amplification is proposed. The basic idea of the circuit is to use a DC current in order to induce an unbalance on the VGS loop of a current mirror. It is demonstrated that the input-output amplification is controlled by a DC current.

Chiral Control of Current Transfer in Molecules

2010
Electron transmission through chiral molecules induced by circularly polarized light can be very different for mirror image structures. This behavior is described in terms of current transfer: the transfer of both charge and momentum. We review recent theoretical developments on the theory of current transfer and discuss related experimental studies of
