End-to-End Ascent-Entry Mission Performance Optimization Using Gaussian Quadrature Collocation
Alexander T. Miller, Anil V. Rao
The performance optimization for a combined ascent-entry mission subject to constraints on heating rate and heating load is studied. The ascent vehicle is modeled as a three-stage…
Nonsingular Euler Parameterizations for Motion of a Point Mass in Atmospheric Flight
Alexander T. Miller, Anil V. Rao
Three parameterizations are developed for modeling translational motion of a point mass in atmosphere flight over a central rotating body. Unlike well-known parameterizations such…
Nonsingular Parameterization for Modeling Translational Motion Using Euler Parameters
Alexander T. Miller, Anil V. Rao
A parameterization is described for quantifying translational motion of a point in three-dimensional Euclidean space. The parameterization is similar to well-known parameterization…
Mesh Refinement Method for Solving Optimal Control Problems with Nonsmooth Solutions Using Jump Function Approximations
Alexander T. Miller, WIlliam W. Hager, Anil V. Rao
A mesh refinement method is described for solving optimal control problems using Legendre-Gauss-Radau collocation. The method detects discontinuities in the control solution by emp…
