Optimal latching control
WebJul 13, 2024 · Results show that the optimal latching control law derived from the Coulomb damping-based model can effectively improve the power capture ability of the raft-type WEC with a hydraulic PTO system. The benefit due to latching control can reach a peak value of 3.04, which is 2 times that introduced by load control.

WebDec 13, 2013 · Abstract: We propose a control algorithm for wave energy converters (WECs) using derivative-free optimization (DFO), with relatively low computational burden and significant improvement in energy generation. The main idea is to consider the energy generation over a time horizon as a function of the latching time and formulate a suitable …
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. chinese buffet lagrange gaWebFeb 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 … chinese buffet lake charles laWebreleased 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 ... chinese buffet lake charlesWebJul 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. chinese buffet lake havasu cityWebLatching control is commonly used in WEC to increase power absorption capacity. Different approaches can be taken to implement latching control. Latching of the WEC can be adjusted based on a sea state or on the wave to wave basis that passes through the WEC. grand designs 2022 canterburyWebApr 2, 2024 · The best control approach to achieve said resonance is known as complex-conjugate control, based on solving the impedance matching problem.
