| Abstract: | This paper aims at describing theoretical and practical aspects of the implementation of 3D active wave absorption (ARA) in a real basin. Implementation of the 3D ARA depends on the combining algorithm and on proper frequency response control through tuned filtering of the system response. The 48-paddle 3D wave generator with Active Reflection Absorption system, recently installed at the Haynes Coastal Engineering Laboratory, uses two signals for waveboard steering with simultaneous reflection absorption. The file with both signals is supplied by a purpose-built GEDAP package. The ARA control loop is closed in an industrial PC running Bosch Rexroth' HyPCoS real-time control software; no special hardware is used. | |
