Modeling and attitude control of CubeSat utilizing moving mass actuators

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...

Novel Attitude Control Challenges for an Earth-Observing CubeSat

This paper presents a novel attitude determination and control solution for a three cube nanosatellite performing science operations in low Earth orbit. The spacecraft is tasked with studying the water content of Earth’s upper atmosphere by taking radiometer measurements along the 183 GHz absorption line. The radiometer must be calibrated against the cold of deep space, and this calibration nec...

Spacecraft attitude control using magnetic actuators

Modeling and Control of Hydraulic Rotary Actuators

The steps for modeling and control of a hydraulic rotary actuator are discussed. Our aim is to present experimental results working with a particular sensing device for angular position as a complement to pressure sensing devices. We provide the steps in experimental system identification used for modeling the system dynamics. The cascade controller designed contains an inner loop for an accura...

Design and Evaluation of the Attitude Determination and Control System for PW-Sat2 CubeSat

PW-Sat2 satellite is a 2kg CubeSat that is being developed by the students from Warsaw University of Technology. The project is a part of activity of the Students’ Space Association from Faculty of Power and Aeronautical Engineering. The satellite will be launched in 2016 in Low Earth Orbit to test the deorbitation method using deployed sail in the end of the mission. The CubeSat will have depl...
