【 摘 要 】

Model tests have been carried out in a wave channel with and without consideration of 2nd order wave components in the control signal for the wave paddle. The wave channel was equipped with a 1:30 sloped bottom starting 57.00 m in front of the paddle. The water depth was 1.00 m during all tests. The Self-Correcting System was proved to be able to suppress unwanted free higher and lower harmonics during the generation process. On the slope measured amplitudes of the 2nd order waves were lower than predicted by 2nd order theory. Commonly used wave height parameters are not influenced significantly by the type of control signal.
