Abstract of the project-team:

The objective of this team is the ultra-low power consumption of electronic circuits. To do that we suggest to study non-uniform event-driven sensors/actuators and parsimonious signal processing in systems. More precisely, one of the objectives is to develop a low-power vision sensor. Such an electronic circuit will be designed at the very beginning of the project. The second theme is about the optimal control of systems equipped with converters. It asks to study non-smooth dynamical systems. For nonlinear control systems, the possibility of updating the control inputs, only when some events occur, will be also investigated. Thus the observation and the control of event-based dynamical systems will be also studied. These events may come from a function of the state or of the measured output only. Finally two demonstrators will be built to illustrate and combine all results obtained in the project. For all axis, optimization objectives will be tackled, as the minimization of numbers of level-crossings that are necessary to recover a signal in a given class of signals.

The applications that we have in mind are embedded systems with ultra-low consumptions. More precisely, the applications include event-driven architectures, as micro-electronic components. The practical applications are medical ones, and minimization of electrical consumption for networks systems. The applications of the event-triggered controls for nonlinear systems, or for non-smooth systems are the control of biomimetic robots (as micro flying artificial insects) and mechanical systems with constraints of first or second order (as the control of dynamical objects with shocks and constraints on the state variables).

This team is supported by the themes Modeling and Simulating the physical world (SIM) and Pervasive Computing Systems (PCS) of Persyval-lab.

PhD Thesis of F. Zobiri

Starting in October 2015

Titre : Optimisation de l’échantillonnage pour le traitement du signal et contrôle de systèmes évènementiels

Encadrants : Brigitte Bidegaray-Fesquet, Laboratoire Jean Kuntzmann et Nacim Meslem, Gipsa-lab

Résumé : Le contexte de cette thèse est l’équipe action E-BaCCuSS (Event-Based Control, Circuits and Processing towards Ultra-Low Power Consumption) qui vient d’être labellisée dans le cadre du laboratoire d’excellence Persyval-lab. Cette équipe-action regroupe cinq laboratoires (CEA-LETI, Gipsa-lab, INRIA, LJK, TIMA) et est donc de nature fortement pluridisciplinaire. Les travaux proposés se situent dans le prolongement de travaux précedents entre les laboratoires LJK et TIMA d’une part sur le traitement du signal pour des systèmes asynchrones à échantillonnage non uniforme, et entre les laboratoires Gipsa-lab et TIMA sur des systèmes de contrôle robuste de la consommation électrique. Ces travaux ont permis de trouver et d'implémenter matériellement des algorithmes efficaces et peu consommant, mais en utilisant des seuils d’échantillonnage standard. Le but de cette thèse est d’optimiser ces algorithmes en utilisant des seuils construits dynamiquement en fonction de l’application et des signaux, et en améliorant les techniques de traitement ou de contrôle. Des applications aux systèmes embarqués sont prévues dans le cadre du projet E-BaCCuSS notamment pour des dispositifs médicaux. La justification mathématique des performances des algorithmes est également un enjeu important pour assurer leur adoption par le monde industriel. Elle fera l’objet d’une attention particulière dans le cadre de la thèse.
