For a heave-pitch-surge three-degrees-of-freedom wave energy converter, the heave mode
is usually decoupled from the pitch-surge modes for small motions. The pitch-surge modes …

Nonlinear parametrically excited (NPE) systems govern the dynamics of many engineering
applications, from cable-stayed bridges where vibrations need to be suppressed, to energy …

This paper presents a solution to the optimal control problem of a three degrees-of-freedom
(3DOF) wave energy converter (WEC). The three modes are the heave, pitch, and surge …

Vibration energy harvesting is the transformation of vibration energy to electrical energy. The
motivation of this work is to use vibration energy harvesting to power wireless sensors that …

This paper presents a nonlinear parametrically excited cantilever beam with electromagnets.
A parametrically excited two-degree-of-freedom (2-DOF) system with linear time-varying …

Parametrically excited systems, where defining system parameters vary periodically with an
independent variable (time), are a popular research topic in engineering. Cable-stayed …

In this paper energy harvesting from vibrating surfaces through electromagnetic induction is
addressed. A double pendulum subject to base excitations generates electrical energy …

Proof-mass actuators are typically used to supply a secondary control force to a supporting
structure for the purpose of improving its performance through active vibration control. These …

The control of a three-degree-of-freedom (3-DOF) wave energy converter (WEC) is
considered in this paper. Recently, several methods have been developed in the literature …

In this article, considering the existing limitations in changing the length of the linear spring
and, on the other hand, the ability to design and manufacture a suitable damper element …
