Accounting for Solar Radiation Pressure in the Hamiltonian Normal Form of the Elliptic Restricted Three-Body Problem
Carson Hunsberger, David Schwab, Roshan Eapen +1
Hamiltonian normal forms allow for the analytical approximation of center manifold trajectories and their invariant manifolds through the separation of the saddle and center subspa…
Comparing Normal Form Representations for Station-Keeping near Cislunar Libration Points
Carson Hunsberger, David Schwab, Roshan Eapen +1
The normal forms provide useful approximations for many trajectories of interest within the circular restricted three-body problem. This paper aims to thoroughly compare two of the…
Stochastic analysis of impulsive thrust uncertainties in the CR3BP
Sharad Sharan, Amit Jain, Roshan T. Eapen +1
This paper employs an alternate dynamical model of the circular restricted three body problem to quantify uncertainties associated with spacecraft thrusting maneuvers. A non-produc…
A Hamilton-Jacobi Approach for Nonlinear Model Predictive Control in Applications with Navigational Uncertainty
Amit Jain, Roshan T. Eapen, Puneet Singla
This paper introduces a novel methodology that leverages the Hamilton-Jacobi solution to enhance non-linear model predictive control (MPC) in scenarios affected by navigational unc…
