The effect of control on the responses of an offshore wind turbine

Abstract

Control logic can be defined as the software platform which provides the basis of applying control demands to the wind turbine. This platform consists of filters, mathematical operators, software computations, signal processing, controllers and all other interactive programs needed to govern the wind turbine. Noticeably, this control logic can affect the behavior of the wind turbine. Specifically, for an offshore wind turbine in which negative damping may happen as a result of a weak controller design, the analysis of the control logic impacts on the machine is of high importance. The goal of this research is to study the behavior of the control logic on an offshore wind turbine.
