On friction effects as a mechanism to induce complex dynamical behavior in earthquakes
(2012)"In this paper we analyze a nonlinear dynamical system that describes the kinetic mechanism between tectonic plates on the crust´s earth undergoing stick slip movement. The analysis includes friction effects and an empirical ... -
Make a PI controller on an 8-bit micro
(2006-01)"This article shows you how to implement a classical PI (proportional-integral) controller on a simple 8-bit microcontroller. To implement the PI controller, we developed specific libraries that make it possible for the ... -
Unveiling uncertain forces in second-order driven oscillators via internal model: a discrete-time feedback
(Hindawi, 2000-02)"Unveil uncertain forces acting into (or onto) systems is a very interesting and old problem. Indeed, a lot effort has been devoted to develop procedures which results in the understanding of the uncertain forces and its ... -
Comparing performance on chaos control via adaptive output-feedback
(2006)"Performance of four controllers is experimentally compared and evaluated in context of chaos suppression. Four output-feedback controllers are used in experi- ments for comparison. First three schemes utilize an adaptive ... -

Generation of multi-scroll attractors without equilibria via piecewise linear systems
(2017-05)"In this paper, we present a new class of dynamical system without equilibria which possesses a multiscroll attractor. It is a piecewise-linear system which is simple, stable, displays chaotic behavior and serves as a model ... -
A note on optimization of chaos suppression via robust asymptotic feedback: accounting control cost
(2000)"This paper deals with the chaos suppression for oscillators in canonical form. The underlying idea is to optimize the robust chaos supression by accounting the control cost. The robust chaos supression is attained by the ... -
