TIME-DELAYED FEEDBACK CONTROL OF TIME-DELAY CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2003
This paper addresses time-delayed feedback control (DFC) of time-delay chaotic systems. To extend the DFC approach to time-delay chaotic system, alter having been successfully used in chaotic systems without time-delays, the standard feedback control (SFC) method is firstly employed to show the main control technique in this paper based on one error ...

Time delay in tunneling: Transmission and reflection time delays

Physical Review A, 1988
The problem of time delay in one-dimensional quantum-mechanical scattering by a potential barrier is studied in the framework of time-dependent scattering theory. It is shown how the concept of sojourn time can be used to define three separate time delays: the time delay for transmission through the barrier, the time delay for reflection, and the total

Time Delay

Remedial and Special Education, 1988
Students labeled mildly handicapped often fail to memorize and retain information such as math facts, sight words, and spellings when taught by traditional instructional procedures. Time delay, a nearly errorless instructional procedure, has been effective in teaching these behaviors to a variety of students.

Robust Time-Delay Control

Journal of Dynamic Systems, Measurement, and Control, 1993
A method is presented to minimize residual vibration of structures or lightly damped servomechanisms. The method, referred to as the proportional plus multiple delay (PPMD) control, involves the use of multiple time delays in conjunction with a proportional part to cancel the dynamics of the system in a robust fashion.

TIME DELAY AND INHOMOGENEITIES

The Ninth Marcel Grossmann Meeting, 2002
Gravitational leasing plays an important role in studing the cosmological parameters, since propagation of light rays in curved spacetime is intrinsically connected to the structure of the universe. In particular,it depends also on the clumps of matter that it encounters on its way from the source to the observer...

Control of time delay processes with uncertain delays: Time delay stability margins

Journal of Process Control, 2006
Abstract In this paper, the stability of time delay processes that have uncertain delays is considered, and the maximum allowable perturbation which may occur in the time delays so as to maintain stability are determined. In particular, the characteristic equations of time delay systems are quasipolynomials, whose roots determine the stability of ...

Fusion of time delayed measurements with uncertain time delays

Proceedings of the 2005, American Control Conference, 2005., 2005
In this paper we consider the problem of estimating the state of a dynamic system from a sequence of observations that are imprecisely timestamped. We argue that this problem can be addressed using the covariance union (CU) technique, and we demonstrate its application in a particular example.
