Abstract : We have conducted research on the modeling and control of nonlinear systems. Our efforts have been directed toward understanding the structure and control of maneuvering nonlinear systems. The prototypical maneuver is a periodic orbit. We have studied the structure of nonlinear systems in the neighborhood of a periodic orbit and discovered necessary and sufficient conditions for transverse feedback linearization of a system about a periodic orbit. In general stable maneuvering can be achieved by by providing for the stability of the transverse dynamics of the system. We have developed techniques for stabilizing the transverse dynamics of a system based on the transverse linearization. We have also developed methods for converting a stable trajectory tracking control law into a stable maneuvering control law.
