Stick-slip chaos in a non-ideal self-excited system
(2003-12-01)
In engineering practical systems the excitation source is generally dependent on the system dynamic structure. In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy ...
CONTROL DESIGN AND ROBUSTNESS ANALYSIS OF A BALL AND PLATE SYSTEM BY USING POLYNOMIAL CHAOS
(Amer Inst Physics, 2014-01-01)
In this paper, we present a mathematical model of a ball and plate system, a control law and analyze its robustness properties by using the polynomial chaos method. The ball rolls without slipping. There is an auxiliary ...
Chaos control and sensitivity analysis of a double pendulum arm excited by an RLC circuit based nonlinear shaker
(2015)
In this paper the dynamical interactions of a double pendulum arm and an electromechanical shaker is investigated. The double pendulum is a three degree of freedom system coupled to an RLC circuit based nonlinear shaker ...
Time-reversal focusing and space-time control of interferences :
(2010-03)
La focalización de ondas acústicas que se propagan por un medio inhomogéneo fue lograda con éxito a través del procedimiento conocido como espejo de reversión temporal (TRM). En este experimento, las ondas salientes son ...
Time reversal mirror and perfect inverse filter in a microscopic model for sound propagation
(Elsevier Science, 2007-09)
Time reversal of quantum dynamics can be achieved by a global change of the Hamiltonian sign (a hasty Loschmidt daemon), as in the Loschmidt Echo experiments in NMR, or by a local but persistent procedure (a stubborn daemon) ...
