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 ... -
On the emergence of chaos in dynamical networks
(2012)"We investigate how changes of specific topological features result on transitions among different bounded behaviours in dynamical networks. In particular, we focus on networks with identical dynamical systems, synchronised ... -
On the stability of AQM controllers supporting TCP flows
(2009)"In this chapter we address the local asymptotic stability of some AQM controllers supporting TCP flows. We first consider a PI controller as AQM strategy. The complete set of PI controllers that stabilizes the linearized ... -
On the transversality of functions at the core of the transverse function approach to control
(2011-12)"The transverse function approach to control, introduced by Morin and Samson in the early 2000s, is based on functions that are transverse to a set of vector fields in a sense formally similar to, although strictly speaking ... -
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 ... -
Open problems related to the Hurwitz stability of polynomials segments
(Hindawi, 2018)"In the framework of robust stability analysis of linear systems, the development of techniques and methods that help to obtain necessary and sufficient conditions to determine stability of convex combinations of polynomials ... -
Output-feedback adaptive control for the global regulation of robot manipulators with bounded inputs
(2013)"In this paper, an output-feedback adaptive scheme for the global position stabilization of robot manipulators with bounded inputs is proposed. Compared to the previous output-feedback adaptive approaches developed in a ... -
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 ... -
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 ... -
Output-feedback proportional-integral-derivative-type control with multiple saturating structure for the global stabilization of robot manipulators with bounded inputs
(2016-09)"An output-feedback proportional integral derivative-type control scheme for the global regulation of robot manipulators with constrained inputs is proposed. It guarantees the global stabilization objective-avoiding input ... -
Performance monitoring of heat exchangers via adaptive observers
(Elsevier, 2007)"In this paper, a method for monitoring the performance degradation in a heat exchanger is presented. This method is based on the use of an adaptive observer which estimates the overall heat transfer coefficient U. The ... -
Preservation of a two-wing Lorenz-like attractor with stable equilibria
(2013)"In this paper, we present the preservation of a two-wing Lorenz-like attractor when in the Lorenz system a feedback control is applied, making two of its equilibria a sink. The forced system is capable of generating ... -
Pseudo-random bit generator based on lag time series
(2014)"In this paper, we present a pseudo-random bit generator (PRBG) based on two lag time series of the logistic map using positive and negative values in the bifurcation parameter. In order to hidden the map used to build the ... -
