Optimal trajectories for the aeroassisted flight experiment
The aeroassisted flight experiment (AFE) is to simulate a transfer from a geosynchronous Earth orbit (GEO) to a low Earth orbit (LEO). Specifically, the AFE spacecraft is released from the Space Shuttle and is accelerated ...
Optimal reorientation of spacecraft using only control moment gyroscopes
Spacecraft reorientation can require propellant even when using gyroscopes since these have momentum saturation limits at which control is lost until thrusters are fired to desaturate them. To eliminate this need and thereby ...
Robust momentum manager controller for space station applications
An innovative methodology to design a robust Control Momentum Gyro (CMG) momentum manager for the International Space Station (ISS) is developed. Unlike most other momentum manager designs, which use either a Linear Quadratic ...
A comparison of transcription techniques for the optimal control of the International Space Station
The numerical solution of Optimal Control Problems has received much attention over the past few decades. In particular, direct transcription methods have been studied because of their convergence properties for even ...
