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. Webpresents a variational formulation of the optimal control prob-lem and methods to solve it. Finally, in Section IV an example device is used to demonstrate the computational gains from using a projected gradient method. Control feasibility and the improvement that optimal active control delivers over optimal latching control is also presented.

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. 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. is david payne channel 9 weatherman married
