This research focuses on the utilization of non-convex, non-smooth optimization techniques to solve nonlinear time variant problems of importance to the Air Force. Typical problems can come from control and management of turbulence, estimation of ocean-atmospheric flow parameters, complex C4ISR network operations, unmanned systems operations and path planning, and optimal maneuvering of aerial and space vehicles.
Research includes (1) studying variational and quasi-variational inequalities for optimal stopping and impulse control problems of sequential decision making; (2) exploring the connection between differential games and H-infinity control in the context of infinite dimensional problems in fluid flow control; (3) studying mixed-integer programming problems for unmanned systems path planning and obstacle avoidance, and dynamic network optimization problems; and (4) dynamic programming analysis for feedback control synthesis of infinite dimensional time dependent physical processes of interest to the Air Force, such as low/high speed aerodynamics and plasma dynamics problems arising in particular in hypersonic range.
