چکیده

The present work addresses the need for an efficient, versatile, accurate and open-source numerical tool to be used during design stage of wave energy converters (WECs). device considered here is heaving point-absorber developed tested by Sandia National Laboratories. smoothed particle hydrodynamics (SPH) method, as implemented in DualSPHysics, proposed since its meshless approach presents some important advantages when simulating floating devices. dynamics power take-off system are also modelled coupling DualSPHysics with multi-physics library Project Chrono. A satisfactory matching between experimental results obtained for: (i) heave response forced via actuator; (ii) vertical forces acting on fixed under regular waves and; (iii) WEC action both actuator force. This proves ability simulate accurately fluid–structure interaction along WEC’s closed-loop control system. In addition, radiation models built from WAMIT compared plotting intrinsic impedance frequency domain, showing that SPH method can employed identification.

Control of Flexible Link Robot using a Closed Loop Input-Shaping Approach

This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a  vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...
