Seminaire de Delphine Bresch Pietri

Thursday 20 of november, at 14h00 salle Jacques Bordet, Delphine will present a part of those works:
Title: Implicit integral equations for modeling systems with a transport delay — Control stakes and open problems

Abstract: Delays are well-known to be often related to transportation of material, e.g., when sensors and actuators are not co-located. In this talk, we focus on a particular class of such transport delay,
satisfying an integral equation involving past values of the process flow rate. We illusrate the relevance of this modeling with experimental data from several fluid flow subsystems of thermal
engines (Exhaust Gas Recirculation, after-treatment devices).

In particular, we present experimental results carried out on an test-bench at GIPSA-lab, Grenoble, to control the mist inside an elongated tube. This test bench consists of a horizontal column
equipped with a mist actuator located at the inlet and fans generating an air flow circulating along the tube. The control objective is to stabilize the mist at the output of the tube actuating
on the wind speed (i.e. the fans velocities). Correspondingly, this set-up involves an integral-type transport delay (between the inlet and the output of the tube) which is also input-dependent.

Finally, we draw some control perspectives and present related open problems.Jeudi 20 novembre, à 14h00 salle Jacques Bordet, Delphine nous présentera une partie de ses travaux :
