Wind energy as one of the renewable energies is serving as an indispensable role in generating new electric power. The worldwide installation of wind farms has considerably increased recently. To extract more wind resources, multi-megawatt wind turbines are usually designed and constructed with large rotors and slender tower. These flexible structures are susceptible to external dynamic excitations such as wind, wave and seismic loads. The excessive vibrations can compromise the wind energy conversion, lead to the structural fatigue damage and even result in the catastrophic failure of wind turbines in harsh environmental conditions. Various control devices have been proposed and used to mitigate the unwanted vibrations of wind turbines to enhance their safety and serviceability. This paper aims to provide a state-of-the-art review of the current vibration control techniques and their applications to wind turbines. Firstly, the widely used control strategies in engineering structures are briefly introduced. Their applications to suppress the adverse vibrations of the structural components of wind turbines, mainly the tower and blades, are then reviewed and discussed in detail. It can be concluded that the vibration mitigation of wind turbines is very challenging due to the fact that the dynamic behaviours of wind turbines are very complicated, which are associated with the aerodynamics, rotation of the blades, interaction between the tower and rotating blades, and soil-structure interaction, etc. Moreover, it is a challenge to straightforwardly use many of the conventional control devices because of the limited spaces in the tower and blades.

作为可再生能源之一的风能在产生新电力方面起着不可或缺的作用。最近，全球范围内的风电场安装量大大增加。为了获取更多的风能，通常设计和建造具有大型转子和细长塔架的兆瓦级风力涡轮机。这些柔性结构易受外部动态激励的影响，例如风，浪和地震荷载。过度的振动会损害风能的转换，导致结构疲劳损坏，甚至导致恶劣环境条件下风力涡轮机的灾难性故障。已经提出了各种控制装置并用于减轻风力涡轮机的有害振动，以增强其安全性和可维修性。本文旨在提供对当前振动控制技术及其在风力涡轮机中的应用的最新研究。首先简要介绍了工程结构中广泛使用的控制策略。然后，将详细讨论并讨论它们在抑制风力涡轮机结构部件（主要是塔架和叶片）的不利振动方面的应用。可以得出结论，由于风力涡轮机的动态行为非常复杂，这与空气动力学，叶片的旋转，塔架与旋转叶片之间的相互作用，以及土壤与结构的相互作用等。此外，
