Pandemic and related constraints

We sincerely hope that by July 2022, we will be able to travel, to present the latest research results and, most importantly, to meet up with colleagues, collaborators and friends in person.

ICDEA 2022 organizing committee is closely monitoring the worldwide situation of COVID-19 (coronavirus). The latest information about the travel conditions to France are available on the page of the Ministery of Foreign Affaires.


IFAC CAO 2022 is organized by L2S (Laboratory of Signals and Systems) at CentraleSupélec within the University Paris-Saclay.

We look forward to seeing you in the Paris-Saclay region!
