The design of controllers for wave energy devices has evolved from early monochromatic impedance-matching methods to complex numerical algorithms that can handle panchromatic seas, constraints, and nonlinearity. However, the potential high performance of such numerical controller comes at a computational cost, with some algorithms struggling to imp...

In order to increase the prevalence of wave energy converters (WECs), they must provide energy at competitive prices, especially when compared with other renewable energy sources. Thus, it is imperative to develop control system technologies that are able to maximize energy extraction from waves, such that the delivered energy cost is reduced. An i...

... Even if the application of SI in wave energy is relatively recent, SI has already been successfully employed in WEC modelling [7]- [10]. In two joint publications [7], [8], SI is used in order to derive a forceto-position model, with a force being the PTO force, and a wave-to-position model of a WEC by using three discrete time parametric structures. ...

... Remark 15 [On the stability ofΣ W ] It is straightforward to show that (x, η, f u ) = (0, 0, 0) is an equilibrium point for (31). Furthermore, given that ∂g(x,η) ∂ x | (0,0) = 0, with g as in (32), the local stability properties of the zero-equilibrium ofΣ W are governed by the linearised equatioṅ ...
