A New Control Method of Active Absorption Wave-maker

摘要：

　　The theory of 2D wave generation with active wave absorption is outlined.A new control method of active absorption wave-maker is established based on the S plane control (SPC)algorithm in this paper.Using SPC,a piston-type 2D numerical wave flume (NWF) simulation program for simultaneous wave generation and active wave absorption is developed with Boundary Element Method (BEM) and Mixed Eulerian-Lagrangian (MEL).The absorbing wave-making contrast simulation tests for regular wave are also carried out in NWF.Simulation results verify that the controller is robust and well effect for absorbing re-reflected wave is obtained in low reflect condition.Meanwhile,stable wave profile can be output by the absorbing wave-maker in a long time when acute reflected waves appear in the terminal of NWF.
