The renewable energy sector witnesses increased demand due to energy crises and climate
change. Wind energy, in particular, is promising for reducing fossil fuel dependence and …

This paper presents a semi-active tuned mass damper (STMD) with acceleration and
relative motion feedbacks that is optimised in the frequency domain to ensure the same …

Semiactive control has received extensive attention because it can attain a similar control
gain as active control while requiring a smaller external power supply. The critical step of …

This work covers selected control issues, including refined force tracking algorithm
formulation, concerning the wind turbine tower-nacelle laboratory model equipped with a …

The paper presents an experimental implementation of an optimal-based vibration control
for a scaled wind turbine tower-nacelle structure. A laboratory model of the approximate …

Wind turbine tower dynamic stress is related to the fatigue wear and reliability of the whole
wind turbine structure. This paper deals with the problem of tower vibration control using a …

In the study we propose and examine a novel concept, eMR-TMD as we call it, replacing a
standard tuned mass damper (TMD) by an electrical harmonic oscillator (RLC circuit). The …

Wind turbines are growing in size in order to reach stronger winds and to produce more
energy, even thanks to longer blades. This leads to bigger and bigger cross dimensions for …

An active mass damper (AMD) was developed that uses a linear motor and coil spring to
reduce the vertical vibration of a long-period cable-stayed bridge subjected to wind and …

This study investigates a newly developed positioning system based on a rotary
magnetorheological damper with power generation capability, comprising an …
