Wind turbines usually present several feedback control loops to improve or counteract some
specific performance or behaviour of the system. It is common to find these multiple …

We investigated the mathematical model of a ferromagnetic cantilever beam containing
patches of piezoceramic materials for vibration energy harvesting. The beam is coupled to a …

Floating offshore wind turbine foundations are based on platforms operated by the oil and
gas industry. However, they are designed and optimized to meet the wind turbines' …

Purpose We investigated the non-linear dynamic behavior of a system for energy production
using ocean wave motion. The compound consists of a linear electromagnetic system …

Recently a floating vertical-axis wind turbine (VAWT) concept that integrates a VAWT with a
steel fishing cage has been developed by leading authors. In order to fathom the kinetic …

The Multiple Timescale Spectral Analysis is a framework relying on the existence of well-
separated timescales in the dynamic response of structures to generalize for higher-order …

Renewable energy devices may operate in complex internal and external conditions, and
engineering analysis is a key element of the design process. Because of the sophisticated …

The objective of this thesis is to evaluate the sensitivity of the tower design with respect to
frequencies. The investigation is done for the floating wind turbine concept OO-Star Wind …

This thesis aims to analyze the dynamic response of a semi-submersible floating wind
turbine under combined wind and ice loads through a coupled analysis. The importance of …
