Cooperative Control of Multiple Spacecraft subject to Measurement Uncertainties and Time Delays
Abstract
Abstract TPOC: Kyle Henderson, AFRL/RVES Attn: Dr. R. Scott Erwin, AFRL/RVES Topic Area: 4 - Space Technologies & Operations Technologies The objective of the proposal is to conduct research into the topic of `Cooperative Control of Multiple Spacecraft subject to Measurement Uncertainties and Time Delays . The research will focus on both translational and rotational motion control using dynamic graph theory based approaches, artificial potential functions to create virtual potential fields, and Lyapunov based control techniques. First, the framework will enforce cooperation among multiple vehicles to synthesize consensus based constrained trajectories (position and attitude) for operation. Robust Lyapunov based control laws will be synthesized to accommodate uncertanties in measurements (orientation, angular velocity, translational position) including time delays in the communication links. The problems that will be specifically solved include the cooperative trajectory tracking, and attitude synchronization. The purpose of this research is to enable smart deployment (and tasking) of space assets in applications such as space surveillance, and monitoring of space objects. The framework, algorithms, and results from this research can serve diverse applications such as, formation flight of multiple aircraft, cooperative target tracking, cooperative ground and air vehicle control for disaster site montoring, accident investigation, traffic monitoring, automatic platooning in future highways such as those envisioned in the Smart Cities program. The impact of the proposed research is wide and far reaching for both DoD and civilian applications. Ro- bust cooperative control laws such as those proposed in this research will enable safe system operation despite uncertainties, bring down operational costs (conserve fuel), allow smart use of resources, allow for agile response to emergencies, and provide better contingency support by exploiting redundancy.
