Iac-12-c1.9.10 Coupled Orbit and Attitude Dynamics of a Reconfigurable Spacecraft with Solar Radiation Pressure

Simulation of Spacecraft Attitude and Orbit Dynamics

In this paper, the simulation model of satellite attitude and orbit dynamics is discussed. The satellite attitude model has been represented in term of a quaternion and a ordinary differential equation is used to describe the satellite orbital motion. The different actuators and sensors have been modeled with suitable faults and failures. The simulation model enables us to consider the satellit...

Integrated Orbit, Attitude, and Structural Control Systems Design for Space Solar Power Satellites

The major objective of this study is to develop preliminary concepts for controlling orbit, attitude, and structural motions of very large Space Solar Power Satellites (SSPS) in geosynchronous orbit. This study focuses on the 1.2-GW “Abacus” SSPS configuration characterized by a square (3.2 × 3.2 km) solar array platform, a 500-m diameter microwave beam transmitting antenna, and an earth-tracki...

Low Earth-orbit satellite attitude stabilization with fractional regulators

Fractional Order Control methods were applied to a three-axis reaction wheels satellite attitude control system. To show the advantages of this method, a comparative study between a Linear Quadratic Regulator and a Fractional Order Control was established through two principal fractional control laws. The aim is to establish an efJicient control law which satisJies a given speczjication and mai...
