Abstract
In this work we study the problem of minimum energy docking maneuvers between two
Floating Spacecraft Simulators. The maneuvers are planar and conducted autonomously in
a cooperative mode. The proposed guidance strategy is based on the direct method known
as Inverse Dynamics in the Virtual Domain, and the nonlinear programming solver known
as Sequential Gradient-Restoration Algorithm. The combination of these methods allows
for the quick prototyping of near-optimal trajectories, and results in an implementable
tool for real-time closed-loop maneuvering. The experimental results included in this
paper were obtained by exploiting the recently upgraded Floating Spacecraft-Simulator
Testbed of the Spacecraft Robotics Laboratory at the Naval Postgraduate School. A direct
performances comparison, in terms of maneuver energy and propellant mass, between
the proposed guidance strategy and a LQR controller, demonstrates the effectiveness of
the method.
