Abstract:

The objective of this research was to contribute to the fundamental understanding of hybrid control systems and to explore the use of hybrid feedback in problems of interest to the Air Force. We aimed to provide a solid, foundational understanding of hybrid systems that will enable the vast potential of hybrid control to be realized. On the analysis side, we investigated the implications of different hybrid semantics, the simulation of hybrid systems, and the interconnection of hybrid systems, all of which are important for understanding hybrid control design and evaluation. On the control side, we focused on synthesis of robust hybrid control systems. Special attention was given to problems involving online decision making, especially for unmanned air vehicles, on time scales that are similar to the natural time scales of the physical system for which decisions are being made. We also investigated the use of hybrid control in traditional feedback loops, including the use of reset control systems, hybrid logic in anti-windup control, and the design of hybrid patchy vector fields.
