Modified L1 Adaptive Control Design for Satellite FMC Systems with Actuators Time Delay

A modified method for satellite attitude control system in presence of novel actuators is proposed in this paper. The attitude control system is composed of three fluidic momentum controller (FMC) actuators that are used to control Euler angles and their dynamics is considered in satellite attitude equations as well. L1 adaptive control is utilized for satellite three-axial ...

Small Satellite Attitude Control Using Linear Moving Mass Actuators

The subject of this research is to study the use of internal moving masses as the primary means of attitude control for a small satellite platform. The goal of this research is to validate the dynamic model formulated in [1] which describes the under-actuated rotational dynamics of a 3U cubesat with two internal orthogonal linearly translating masses. Models have been developed to simulate angu...
