WebSep 1, 2010 · The principle of latching control principle is to lock the motion of the body when its velocity vanishes at the end of one oscillation, and waiting (over a time that has to be Tsim = Tsim (11) where Tsim is the dimensional simulation duration defined by the user and g the gravitational constant. WebThe improvement of the WEC performance due to latching control is studied. Compared to the performance under simple resistive control, the three latching control strategies show almost equivalent control effect, leading to an average increase of the maximum relative capture width by around 70% and an average decrease of the optimal power take ...

An on/off PTO force is applied by means of a … 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.
WebJan 27, 2024 · To perform on-line optimal control, a force control has acted as a controller and TD coefficients are tuned at a proper rate significantly after specific number of episodes. The power of suggested TD methods is compared to PGM, IPOPT and with other learning control strategies.
