The subject of the paper is synthesis of a robust controller of the load swing during motion of overhead cranes. The approach implements fuzzy partition to the state variables. Stability is secured by employing the Lyapunov theory. The proposed methodology is the most appropriate for the presented problem since exact knowledge about the plant parameters is not needed. Numerical tests show the feasibility...
This paper introduces an open source instant feedback system using wireless messaging technologies. The system targets users' in-hand technologies and allows their participation in any feedback process through simply sending an SMS message or through a dedicated mobile application. Additionally, the system provides an advanced tool for authoring questions, visualizing results, viewing statistics and...
