The aim of this proposal is to discover energy efficient control laws for vibration suppression with the goal of running such systems using harvested energy or a combination of harvested and stored energy by exploiting nonlinearity in both the harvesting mechanism and in control law formulation. It is proposed to investigate the concept of using harvested energy to control the vibration response of flexible structures. Structural components in bridges, airplanes, buildings, wind turbines, etc. are flexible and hence are easily disturbed into vibration from a variety of sources. Often the best solution is a passive one, but in many circumstances performance and safety demand the use of semi-active or active control. The major roadblock in using active control is the requirement for an external power source. Here we propose to investigate the possibility that ambient energy might be harnessed, stored and recycled to provide the energy needed to mitigate vibrations through low power nonlinear control laws, enabling better performance of structures in extreme conditions (wind storms, earthquakes, gusts, etc.).

该提案的目的是发现抑制振动的节能控制定律，目的是使用收获的能量运行此类系统，或通过在收获机制和对照定律制定中利用非线性来运行收获和存储的能量。建议研究使用收获能量来控制柔性结构的振动响应的概念。桥梁，飞机，建筑物，风力涡轮机等中的结构组件是柔性的，因此很容易被各种来源扰动到振动中。通常，最好的解决方案是被动的解决方案，但是在许多情况下，性能和安全要求使用半活动或主动控制。使用主动控制的主要障碍是对外部电源的要求。在这里，我们建议研究环境能量可以通过低功率非线性控制定律来利用，存储和回收的环境能量，以提供减轻振动所需的能量，从而在极端条件下（风暴，地震，阵风，阵风等）更好地性能性能。
