Hyperchaotic encryption based on multi-scroll piecewise linear systems
(2015)"A hyperchaotic multi-scroll piecewise linear system in R4 is binarized to generate a pseudo-random sequence which encrypt a grayscale image via symmetric-key algorithm. The sequence is analyzed throughout statistical tests ... -
On the controllability of networks with nonidentical linear nodes
(Oxford University Press, 2016)"The controllability of dynamical networks depends on both network structure and node dynamics. For networks of linearly coupled linear dynamical systems the controllability of the network can be determined using the ... -
Opamp-based synthesis of a fractional order switched system
(2016)"The analysis, design and circuit synthesis of a fractional order switched system is presented in this paper. That system is capable of showing chaotic oscillations with a fractional order less than three, i.e., 2.4. The ... -
Output-feedback proportional-integral- derivative-type control with simple tuning for the global regulation of robot manipulators with input constraints
(The Institution of Engineering and Technology, 2015)"An output-feedback proportional-integral-derivative-type control scheme for the global position stabilisation of robot manipulators with bounded inputs is proposed. It guarantees the global regulation objective avoiding ... -
Global trajectory tracking through static feedback for robot manipulators with bounded inputs
(2009)"In this work, two globally stabilizing bounded control schemes for the tracking control of robot manipulators with saturating inputs are proposed. They may be seen as extensions of the so-called PD+ algorithm to the bounded ... -
A natural saturating extension of the PD-with-desired-gravity-compensation control law for robot manipulators with bounded inputs
(2007)"This paper proposes a natural saturating extension of the proportional-derivative (PD) with desired gravity compensation (PDdgc) control law for the global regulation of robot manipulators with bounded inputs. Compared ... -
Adaptive observers with persistency of excitation for synchronization of chaotic aystems
(2009)"We address the problem of master-slave synchronization of chaotic systems under parameter uncertainty and with partial measurements. Our approach is based on observer-design theory hence, we view the master dynamics as a ... -
Global finite-time stability characterized through a local notion of homogeneity
(2014)"In this work, a notion of local homogeneity is formally defined. Important results involving homogeneous functions or vector fields are reformulated in the consequent local context. In particular, global finite-time ... -
Adaptive tracking control of chaotic systems with applications to synchronization
(2007)"We address the problem of controlled synchronization of a class of uncertain chaotic systems. Our approach follows techniques of adaptive tracking control and identification of dynamic systems from recent developments of ... -
A family of hyperchaotic multi-scroll attractors in Rn
(2014)"In this work, we present a mechanism how to yield a family of hyperchaotic multi-scroll systems in based on unstable dissipative systems. This class of systems is constructed by a switching control law changing the ... -
Instrumentation of a bicycle without driver for experimental testing of automatic control
(2016)"In this paper, the instrumentation of a riderless bicycle prototype for control purposes is addressed. The proposed instrumentation is based on the mathematical model of a bicycle, in which the dynamical variables correspond ... -
Output-feedback global continuous finite-time and exponential stabilization of bounded-input mechanical systems
(2017)"This work proposes an output-feedback global continuous controller for the finite-time or (local) exponential stabilization of bounded-input mechanical systems. The control design is carried out within the analytical ... -
Chua´s circuit and its characterization as a filter
(2014)"This article deals with Chuaʼs circuit characterization from the point of view of a filter based on the concept of piecewise linear functions. Furthermore, experiments are developed for teaching electronic systems that ... -
Observer-less output-feedback global continuous control for the finite-time and exponential stabilization of mechanical systems with constrained inputs
(2017)"An observer-less output-feedback global continuous control scheme for the finite-time or (local) exponential stabilization of mechanical systems with constrained inputs is proposed. The approach is formally developed ... -
Information entropy production of maximum entropy markov chains from spike trains
(MDPI, 2018)"The spiking activity of neuronal networks follows laws that are not time-reversal symmetric; the notion of pre-synaptic and post-synaptic neurons, stimulus correlations and noise correlations have a clear time order. ... -
Large deviations properties of maximum entropy markov chains from spike trains
(MDPI, 2018)"We consider the maximum entropy Markov chain inference approach to characterize the collective statistics of neuronal spike trains, focusing on the statistical properties of the inferred model. To find the maximum entropy ... -
Bounded positive control for double-pipe heat exchangers

Robust synchronization of a class of uncertain complex networks via discontinuous control
(2012)"We propose robust controller designs to synchronize networks with uncertainties in their node dynamics and their connections. We consider two situations: in the first, we assume that the effect of uncertainties vanishes ... -
