Ricardo Bencatel received his degree in Mechanical Engineering and his Ph.D degree in Electrical and Computer Engineering from the University of Porto, Portugal, in 2006 and 2012. He was a postdoctoral researcher at the University of Michigan, Ann Arbor, MI, USA, until 2016, where he also lectured the course Flight Dynamics and Control during 2 semesters. He is presently the technical director at 4DC Tech, Portugal, with research interests in control applications to foiling boats, unmanned aircraft, and automotive systems. Ricardo Bencatel started working with unmanned aircraft in 2005, taking important technical roles in projects (AsasF and PITVANT) focused on the development of automatic control methods for heterogeneous teams of aircraft, at the University of Porto and in close collaboration with the Portuguese Air Force. His PhD thesis titled Perpetual Flight in Flow Fields discusses how flight control can be tailored to harvest energy from the wind and other atmospheric phenomena. At the University of Michigan, he got involved in several projects involving the control of multiple rotary wing aircraft. That experience together with the continued study of fixed wing aircraft dynamics and control lead him to start a personal project with VTOLs, focused on the control of smooth transitions between vertical and horizontal flight modes. Most recently, Ricardo Bencatel has been applying his flight control know how to the automatic control of naturally unstable hydro-foiling boats, with clients like SeaBubbles and several America's Cup teams. He has designed, implemented, and validated in operational boats controllers to track the ride height, pitch, and roll, even in challenging sea conditions. He has also worked on automatic course control, as a step towards automatic driving.
