This talk explores two distinct classes of hybrid c ontrollers and their application in aerial vehicle control: synergistic hy brid feedback and event-triggered control. Synergistic hybrid feedback is a hybrid control strategy that relies on the definition of a collection of Lyapunov functions and feedback pairs that guarantee global asymptotic st ability of a desired setpoint by switching operating modes near undesired equilibria. We show that this approach can be used to overcome the topolog ical constraints to global asymptotic stabilization on compact manifolds\, enabling global trajectory tracking for aerial vehicles\, robust obstacle avoidance\, global agent synchronization\, and other applications. We wil l also look into hybrid systems models for event-triggered control systems and show that there are some benefits to this approach. In particular\, w e show that nominally well-posed event-triggered control systems with comp lete discrete solutions may exhibit arbitrarily small separation between s ampling events under the influence of arbitrarily small state perturbation s\, and we present some possible solutions to this problem\, such as time- regularization\, state-space regularization and model-based event-triggere d control.\n\n- Biographie : Pedro Casau is a Researcher at IT-Instituto d e Telecomunicacões and an Assistant Professor at the Department of Electr onics\, Telecommunications and Informatics of the University of Aveiro\, P ortugal. He received the B.Sc. in Aerospace Engineering in 2008 from Insti tuto Superior Técnico (IST). In 2010\, he received the M.Sc. in Aerospace Engineering from IST and enrolled in the Electrical and Computer Engineer ing Ph.D. program at the same institution which he completed with distinct ion and honour in 2016. He held the Research Assistant position at the Uni versity of Macau and was a Research Fellow at the Institute for Systems an d Robotics in Lisbon. He participated in several national and internationa l research projects on guidance\, navigation and control of unmanned air v ehicles (UAVs) and satellites. His current research interests include nonl inear control\, hybrid control systems\, networked control systems\, event -triggered control\, vision-based control systems\, controller design for autonomous air-vehicles and spacecraft systems.\n\n \;\n\nTEAMS link: https://teams.microsoft.com/l/meetup-join/19%3ameeting_MjdjNWNlNzYtYjFiYS0 0NDZmLWE1MDItYzhiZjY3YWJkM2Vm%40thread.v2/0?context=%7b%22Tid%22%3a%221587 16cf-46b9-48ca-8c49-c7bb67e575f3%22%2c%22Oid%22%3a%22955ae724-3c70-4f81-8a 92-327e1dc5af57%22%7d CATEGORIES:Séminaire projet MODELE LOCATION:CRAN - ENSEM\, 2\, Avenue de la Foret de Haye\, Voandoeuvre-les-Na ncy\, 54516\, France X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=2\, Avenue de la Foret de H aye\, Voandoeuvre-les-Nancy\, 54516\, France;X-APPLE-RADIUS=100;X-TITLE=CR AN - ENSEM:geo:0,0 END:VEVENT BEGIN:VTIMEZONE TZID:Europe/Paris X-LIC-LOCATION:Europe/Paris BEGIN:DAYLIGHT DTSTART:20240331T030000 TZOFFSETFROM:+0100 TZOFFSETTO:+0200 TZNAME:CEST END:DAYLIGHT END:VTIMEZONE END:VCALENDAR
