Design of Longitudinal Control for Reduced-G Atmospheric Flight
Master Thesis Research, KAUST, RISC Lab, Department of Mechanical Engineering, 2023
This work proposed a triple-integral flight control framework for a zero-gravity flight using a proof-mass-tracking approach. A triple-integral control strategy is adopted to overcome unknown, quadratically increasing drag. Furthermore, to avoid the non-minimum phase characteristics of aircraft longitudinal dynamics (see below), the position deviation from the inertial reference is redefined such that the closed-loop system is minimum phase.
