This project addresses the development of a hierarchy of models for unsteady aerodynamics, in a framework that is suitable for control design. The ultimate goal is to use these models for the design of flight controllers, for instance to accurately track a trajectory in the presence of large disturbances. Classical aerodynamic models by Theodorsen and Wagner were shown to be accurate in many cases, but break down at high angles of attack or for very rapid maneuvers. Methods were developed to perform balanced model reduction without the need for adjoint information, and for systems with periodic motions (such as vortex shedding). These were used to develop models of unsteady pitching and plunging maneuvers that are well-suited to control design techniques. The methods were developed for linearized models (small-amplitude motions) but also perform well for large-amplitude maneuvers.
