   Nyckelord :Thrust measurements; cold gas propulsion; micro thrusters; hanging pendulum; CubeSat; Dragkraftsmätning; kallgasframdrivning; mikrodysor; hängande pendel; CubeSat;

   Sammanfattning : Measuring the thrust of cold gas micro-thrusters, due to the small magnitude of the generated force, is a challenging task, and to obtain satisfying quality of results usually careful adjustments of the setup has to be performed. The work presented in this paper aims at improving the quality of such measurements at the GomSpace Sweden company. LÄS MER

3. 2. Control of Torsionalpendulum on Containercranes

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Nyckelord :Reglerteknik; STS-crane; skew-angle; torsional pendulum; MPC-control; LQG-control; statefeedback control; kalman estimation; Reglerteknik;

   Sammanfattning : A container crane of STS-type, Ship To Shore, consists of a spreader hanging underneath a railrunning trolly. As the container is under the influence of wind, it is likely that it starts to turn in a torsional pendulum. This report handles how the torsional pendulum of a container crane can be damped. LÄS MER
