This work is focused on the multilevel control of the population confinement in the city of Buenos Aires and its surroundings due to the pandemic generated by the COVID-19 outbreak. The model used here is known as SEIRD and two objectives are sought: a time-varying identification of the infection rate and the inclusion of a controller. A control di...
With data-driven control it is possible to design a controller for systems with non-parametric models. The intermediate step of modelling or identification of the system is not necessary, because a non-parametric model of the system can be obtained by means of experimental data. In the linear time-invariant (LTI) framework, these non-parametric mod...
In this paper, the problem of fault diagnosis for a satellite formation flight is considered. A scheme is investigated for fault detection, isolation, and estimation of a class of nonlinear systems. In this scheme, we consider the model uncertainty, input and environmental disturbances. For fault detection, a nonlinear observer is designed to minim...
Max-plus algebra is an algebra that is entirely based on the mathematical operations max(a,b) and a+b, hence the name max-plus algebra. It can be used to describe Discrete Event Systems (DES) that require scheduling, such as a printer or train network. Max-plus algebra is studied because of its interesting properties, which make some non-linear sys...

Over the past four decades, shrimp aquaculture has turned into a major industry providing jobs for millions of people worldwide especially in countries with large coastal boundaries. While the shrimp industry continues to expand, the sustainability of shrimp aquaculture has been threatened by the emergence of diseases. Diseases caused by single-str...
This PhD is mainly focussing on feedback control of complex systems, i.e. coupled MIMO systems with nonlinear dynamics. Two setups are available: (i) an actuated wing in a wind tunnel and (ii) a magnetic bearing. The goal is to come up with an integrated approach to identification and control of a mechatronic system. Linear Parameter Varying (LPV) ...
Over the past years, the automotive industry has seen a constantly increasing level of automation of automotive vehicles. This increasing level of automation contributes to an increasing safety in traffic and a reduction of traffic congestions due tio faster response times and higher reliability, with respect to the human driver. The automation of ...
In this short work, the problem of designing a Fault Tolerant dynamic output-feedback controller for Semi-Active Suspension Systems is considered. The suspension system is considered as subject to Loss of Effectiveness (time-varying) faults on each of the four actuators (suspension's dampers). An active reconfiguration fault tolerant scheme is prop...

Limited data are currently available on antiretroviral pharmaco- kinetics in breast milk (BM) and in breastfed infants’ blood. To explore these parameters in patients in Mali, we measured plasma antiretroviral levels in human immunodeficiency virus (HIV)–infected mothers and their breastfed infants over 6 months. We specifically analyzed the concen...
