Optimal latching control
WebApr 2, 2024 · The best control approach to achieve said resonance is known as complex-conjugate control, based on solving the impedance matching problem. As we will explain later, this control always achieves optimal power absorption since it regulates the system reactance and resistance simultaneously. Webreleased at a favorable time. In [4] an optimal sequence of latching/unlatching commands is computed to maximize extracted energy in a simplified model. Since then, optimal latching control has been widely applied to single DOFs devices [2], [5]–[7] as well as WECs with multiple DOF [6], [8], [9]. However, the effectiveness of latching ...

The benefit due to latching control can reach a peak value of 3.04, which is 2 times that introduced by load control.
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.
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. WebAs a kind of phase control strategy, latching control has been widely applied to point-absorption wave energy converters (WECs). However, the determination of latching …
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 …
WebJul 29, 2016 · Latching is a discrete controller that locks the device motion at its extrema for an appropriate latching duration so that the amplitude of motion is exaggerated (Budal et al. 1979 ). As a consequence, the wetted surface experiences greater changes, exaggerating the relevance of nonlinearities. binaxnow covid - 19 antigen self testWebApr 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.
