Wave Carpet Controls Design Optimization

Abstract

To assess CalWave's submerged Wave Carpet Technology for system performance advancement,
CalWave seeks to test advanced controls methodologies on a simplified wave carpet model, which
potentially can be used in further research to leverage the design to a full wave carpet assessment using
the discrete element method. Thus, the foremost flexible structure of the Wave Carpet design is split into
articulated multiple discrete, solid pieces and moreover, a single piece connected to a 1DOF (Heave) only
PTO is being subject to performance advancing control assessment.

This report details the results of simulation studies carried out on two simplified models of the wave
carpet using discrete element method. First, we consider the case of a single plate absorber and extend
this example to a two-plate absorber configuration. Performance benchmarking results are presented for a
deep-water DOE reference site.
