Spacecraft Dynamics and Control

Research focuses on spacecraft dynamics and control, particularly where attitude control is effected by applying torques to internal rotors such as reaction wheels, momentum wheels, and control moment gyros, and where energy dissipation is achieved using damping mechanisms. The analysis of these problems involves nonlinear differential equations which in many cases may be expressed as a noncanonical Hamiltonian system, or as a perturbation of such a system. Using standard applied mathematics techniques, including special functions, averaging, multiple scales, WKB, continuation, and Lyapunov-Schmidt reduction, I have obtained new insights into several of these spacecraft problems. These techniques are also applicable to other problems involving rotating mechanical systems of coupled rigid and flexible bodies, such as human body kinetics, rotor dynamics, machine vibration suppression, and flywheel energy storage devices. This research has been supported by the Air Force Office of Scientific Research, the Air Force Research Laboratory, the Space Warfare Center, the Space and Missile Center, NASA Goddard Space Flight Center, and the National Science Foundation


Two space dynamics-related laboratories exist at Virginia Tech. The Space Systems Simulation Laboratory includes two spherical air bearings with approximately 150kg payload each, and allows experimental verification of algorithms and control laws involved in the large-angle, three-dimensional motion of rigid and flexible bodies using internal and external torques, along with distributed control and inter-satellite communications. The Satellite Tracking Laboratory is an education-focused lab, and includes computers and an amateur satellite ground station. Students in space-related courses can perform a variety of experiments involving actual satellites, aimed at strengthening their understanding of space dynamics, state estimation, motion prediction, and space physics, and the effectsthese principles have on the design and operation of spacecraft.

Spacecraft Design and Space Mission Design

Especially interested in projects that give students hands-on experience in designing, building, and testing space payloads, including systems for sounding rockets, high-altitude balloons, and orbital missions.
