WebJul 31, 2014 · This paper evaluates the theoretical application of nonlinear model predictive control (NMPC) to a model-scale point absorber for wave energy conversion. The NMPC strategy will be evaluated against a passive system, which utilizes no controller, using a performance metric based on the absorbed energy. WebFeb 24, 2009 · Optimum reactive control, contrary to sub-optimal latching phase control, requires ability for reversing the energy flow through the power take-off machinery. Computed results show that, for a typical wave of 0.5 m amplitude and 9 s period, the maximum absorbed power is 24, 137, and 172 kW for the cases of no phase control …
WebJan 22, 2024 · As a kind of phase control strategy, latching control has been widely applied to point-absorption wave energy converters (WECs). However, the determination of … WebAn input-output relation is derived through the observable canonical form of the state equations of the controlled object, and an improved optimal regulator theory is applied to the relation. The controller consists of proportional actions, integral actions, difference actions and compensating actions for input delay times.

WebA weak modelling is used to describe latching control prior to applying the optimal command theory. These methods are applied to two different WECs. The first one is a generic one degree of freedom wave energy converter, an heaving buoy, and the second one is the four degrees of freedom wave energy converter called SEAREV.
WebApr 1, 2006 · Latching control consists in locking the motion of the body at the very moment when its velocity vanishes at the end of one oscillation, and waiting for the most favorable situation to release the body. The determination of the duration during which the system remains locked is the problem to be solved.
