The inerter is a new passive mechanical device whose use has been pioneered for suspension systems in the Formula One Industry. There is interest to apply such methods to large systems e.g. earthquake damage mitigation in tall buildings, space tethers, railway suspensions. The motivation for this project is the control vibration in very long high aspect ratio drillstrings, which cause costly damage to mechanical and electronic components of the drillstring. The research seeks both a general famework to apply advances mechanical control methods to such problems and specific solutions for the motivating example. Opportunities exist for experiments testing of promising methods resulting from the research. The project falls under the control engineering EPSRC research area and has many common elements with other areas: complex dynamics, modelling of nonlinear effects, implementation constraints for control solutions.

惯性器是一种新型的被动机械装置，其使用已率先用于一级方程式行业的悬架系统。有兴趣将这样的方法应用到大型系统，例如，高层建筑，空间系绳，铁路悬挂的地震破坏减轻。该项目的动机是在非常长的高纵横比钻柱中控制振动，这会对钻柱的机械和电子部件造成昂贵的损坏。本研究旨在寻求一个通用的框架，以应用先进的机械控制方法来解决这些问题和具体的解决方案，激励的例子。有机会对研究产生的有前途的方法进行实验测试。该项目福尔斯控制工程EPSRC研究领域，与其他领域有许多共同点：复杂动力学，非线性效应建模，控制解决方案的实施约束。
