| Abstract | The paper presents a new technique for the generation of tailored design wave sequences in extreme seas which are simulated experimentally under laboratory conditions. The physical wave field is fitted to predetermined global and local target characteristics designed in terms of significant wave height, peak period as well as wave height, crest height and period of individual waves. The generation procedure is based on two steps: Firstly, a linear approximation of the desired wave train is computed by a sequential quadratic programming method which optimizes an initially random phase spectrum for a given variance spectrum. The wave board motion derived from this initial guess serves as starting point for directly fitting the physical wave train to the target parameters. The Subplex method is applied to improve systematically a certain time frame of the wave board motion which is responsible for the evolution of the design wave sequence. The discrete wavelet transform is introduced to reduce significantly the number of free variables to be considered in the fitting problem. Wavelet analysis allows one to localize efficiently the relevant information of the electrical control signal of the wave maker in time and frequency domain. |
