The dynamical environment on the surface of a rotating, massive ellip-soid is studied, with applications to surface motion on an asteroid. The analysis is performed using a combination of classical dynamics and geometrical analysis. Due to the small sizes of most asteroids, their shapes tend to differ from the classical spheroids found for the planets. The… (More)

The optimal control of a spacecraft as it transitions between specified states in a fixed amount of time is studied. We approach the solution to our optimal control problem with a novel technique, treating the resulting system for the state and adjoints as a Hamiltonian system. We show that the optimal control for this system can be found once the F 1… (More)

In this paper we present a general framework that allows one to study discretiza-tion of certain dynamical systems. This generalizes earlier work on discretization of Lagrangian and Hamiltonian systems on tangent bundles and cotangent bundles respectively. In particular we show how to obtain a large class of discrete algorithms using this geometric… (More)

Periodic orbits are studied using generating functions that yield canonical transformations induced by the phase flow as defined by the Hamilton-Jacobi theory. By posing the problem as a two-point boundary value problem, we are able to develop necessary and sufficient conditions for the existence of periodic orbits of a given period, or going through a… (More)

Periodic orbits are studied using generating functions. We develop necessary and sufficient conditions for existence of periodic orbits of a given period or going through a given point in space. These conditions reduce the search to either solving a set of implicit equations, which can often be done graphically, or finding the roots of an equation of one… (More)

A methodology for solving two-point boundary value problems in phase space for Hamil-tonian systems is presented. Using Hamilton-Jacobi theory in conjunction with the canonical transformation induced by the phase flow, we show that the generating functions for this transformation solve any two-point boundary value problem in phase space. Properties of the… (More)

This paper focuses on applications of a general methodology that we developed for solving two-point boundary value problems. Using the Hamilton-Jacobi theory in conjunction with canonical transformation induced by the phase flow, we proved that the generating functions for this transformation solve any two-point boundary value problem in phase space. This… (More)

The dynamics of reconfiguring a formation of spacecraft is studied. We pose the problem as a two-point boundary value problem where the initial and final positions and times are known and the necessary velocities for the reconfiguration transfers must be found. We present an algorithm that solves this problem for reconfiguration about a nominal trajectory… (More)
