Active tuned mass dampers for control of in-plane vibrations of wind turbine blades

Abstract: This paper investigates the use of active tuned mass dampers (ATMDs) for the mitigation of in‐plane vibrations in rotating wind turbine blades. The rotating wind turbine blades with tower interaction represent time‐varying dynamical systems with periodically varying mass, stiffness, and damping matrices. The aim of this paper is to determine whether ATMDs could be used to reduce in‐plane blade vibrations in wind turbines with better performance than compared with their passive counterparts. A Euler–Lagrangian … Show more

“…tuned liquid column dampers) can be used to reduce these undesirable fatigue loads. These devices may be fully passive [266,267] or semi-actively controlled [268,269]. Other active control methods, such as individual control of each blade pitch angle, can also be implemented [260,270,271].…”

“…Staino et al [21] [22]proposed an active tendons mounted inside blade tip which give a variable active control force to mitigate edgewise vibration.Fitzgerald at al. [24]investigated active TMD for mitigating edgewise vibrations.Fitzgerald and Basu [25] further proposed a cable connected active TMD to suppress edgewise vibrations.However,both semi-active and active control solutions need relatively complicated controller configurations and some amount of power input.Due to the large centrifugal acceleration of the rotating blade,the TLCD with small mass ratios could effectively mitigate edgewise vibrations.Zhang et alproposed a tuned liquid column TLCD equipped inside a rotating blade [26].Basu et al [27] investigate a circular TLCD for edgewise vibration.…”

“…As a consequence, accurate tuning of the natural frequency of the damper to the natural frequency of the primary structure may become difficult, and small deviations from the optimal tuning may result in poor control performance. Further, tuning of the damper to the rotational frequency of the turbine (which is generally associated with harmonic components that mainly dominate the blade response) is not feasible, as it will lead to instabilities in the TMD-blade coupled system [14].…”

“…Investigations on the use of synthetic jet actuators [16], microtabs and trailing edge flaps [17,18] have also been considered by researchers. Active control strategies have been proposed by Staino et al [19] and Fitzgerald et al [14]. The control hardware takes advantage of the fact that the structure of the blade is hollow in nature.…”
