Dynamic inversion control approach for high-mach trajectory tracking

This short paper describes some work related to the NASP program that was performed by the author and coworkers several years ago. The original motivation was to understand how atmospheric variations and dynamic uncertainties can affect trajectories of the NASP vehicle during atmospheric ascent. In an earlier paper [1] the author presented an analytic technique used in conjunction with the algorithms described below to perform perturbed trajectory analyses. The subject of the current paper is the approximate models and the tracking and control strategies used to generate the ascent trajectories. No perturbation analyses are presented here - those results might be published later.
