Real time hybrid modeling as a structured approach of implementing a real time control system has been proven as an efficient strategy to assess and optimize wave energy converter. In this paper an existing real time hybrid modeling framework for wave energy converter is reviewed, in which the main problem is divided into multiple sub-domains. Each sub-domain uses a preferred method, e.g. experimentally and/or computationally, which contributes to solve the main initial problem as a whole. An interface including actuators and sensors enables the simultaneously running sub-domains to communicate in a closed control loop in “real time”. Specifically, the entire power takeoff of a novel WEC called the “Wave Carpet”, which is classified as a submerged pressure differential device, is shifted into the computational domain. The interaction of the WEC’s absorber unit with incident waves is left in the experiment due to its highly nonlinear characteristics. An extended setup allows to reveal further optimization potential of the novel converter design as a case study. Results of the converter behavior under variable wave states, and for different characteristics of the simulated PTO units are presented. In particular, the presented results show the expected broad band absorption capability of the Wave Carpet by closer examination of the influence of variable PTO unit resistance coefficients on the total, and also on the individual units’ performance.
