Abstract [en]

This master thesis describes the design of a detumbling and aerostable control system for CubeSats and the designed control system is validated by operating the simulation in Matlab. A CubeSat named Dsat has been designed to implement aerofoils and it operates in Low Earth Orbit, thus the attitude of the CubeSat can be controlled by using aerostability. In addition, Dsat also needs a detumbling control system to stabilized it after deployment. Thus Dsat is used to demonstrate the detumbling and aerostable control system which is able to be implemented in other CubeSats. Firstly, a detumbling and an aerostable control system concepts for CubeSats are presented respectively, consequently each of the control scheme is explained. Then the hardware selection for the control system is carried out. Furthermore, a 6-DOF control simulation is implemented to assess and validate the control system design in Matlab environment. In addition, the simulation result was illustrated and investigated. The results of the simulation indicate that both the detumbling and aerostable control system meet the design requirement from preliminary design review. In addition, the detumbling time has a large margin. The detailed analysis on the result of aerostable control is also carried out. Finally, the future work required to finalize the development of aerostable and detumbling control system is outlined.
