Nonlinear control can improve a system's performance and robustness. This is especially useful for ocean, atmospheric, and space vehicles which operate in uncertain and widely varying conditions. Ongoing research focuses on the development of energy-based nonlinear control design and analysis methods for mechanical systems, including vehicles.
Robotics and Autonomy
Aerospace and ocean robots, specifically unmanned air vehicles (UAVs), unmanned surface vehicles (USVs), and autonomous underwater vehicles (AUVs), are used in a growing variety of military, scientific, and commercial applications. Ongoing research focuses on perception and planning, guidance and control, and reliability of autonomous ocean and atmospheric vehicles.
Atmospheric and Ocean Vehicle Dynamics
Motion models and analysis tools for conventional atmospheric and ocean vehicles are well developed. Deformable, multibody vehicles -- including biomimetic air and ocean vehicles -- are more challenging to engineer, but their agility and efficiency motivates the development of new design and analysis tools.
