Utilizing Chaotic Transport for Trajectory Generation
Shane Ross, Virginia Tech
Due to limitations of control and the desire for fuel-efficiency, it is necessary to identify dynamical channels in natural flows for transport of agents, e.g., sensor platforms or delivery vehicles. Sophisticated methods have been developed for spacecraft mission design, taking advantage of non-Keplerian gravitational dynamics to find a network of passageways by which a spacecraft can travel over large distances while expending very little energy. However, the idea of using rich natural dynamics to find optimal routes has application to other environments, such as those found in the atmosphere and oceans. The ability to navigate agents efficiently is important to keep operational costs low and becomes essential when the agent's velocity relative to the flow is smaller than or comparable in magnitude to the flow, e.g., gliders in the ocean or planetary atmospheres.
