Considering the heterogeneous aspect of a sensor node, the developed model allows comparing different node configurations in order to make the best choice of components according to the specifications of the application. Therefore, our model allows identifying the need to design specific element or to use Components Of the Shelf
This paper presents the first results of a research intelligent micro sensors in order to alleviate the fatigue loads project leaded by LIPSI-ESTIA concerning the use of intelligent experienced by the WTs blades. Only first simulation tests micro sensors to optimize the design of Wind Turbines (WTs) ee ren ed heW e. O nly ir simulation tests controllers. The sensors situated on the blades are above all used to alleviate WT fatigue loads in above rated wind speed operating hardware in the loop will be realized in the next months. area. Two LQG controllers are designed. One is associated to a This article describes the framework of the presented results sensor situated in the tower. The second controller is associated in section 2. Section 3 deals with the explanation about the to sensors placed at the end of the blades. Some simulations are LQG controllers developed until now. In section 4, simulation realized on a model of a two-bladed WT. They show that the second controller with sensors placed on the blades allow considerably alleviating WT fatigue loads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
