Vibration is a widespread phenomenon in a wide range of systems such as vehicles, buildings, robots, and spacecraft. Undesirable vibrations, if not properly controlled, may cause deterioration in the system performance, and even cause damage and loss of life and property. In recent years, vibration control techniques to protect systems against the harmful effects of vibration have been proposed based on three categories of actuators (passive, semi-active, and active) combined with advanced control algorithms. Recently, a new passive mechanical element, called the inerter, has been demonstrated to be advantageous for many mechanical systems, and has drawn much attention from both academia and industry.
An inerter is a two-terminal mechanical device, which generates a force proportional to relative acceleration. It was originally proposed by Smith from Cambridge University in 2002, and successfully deployed in Formula One racing in 2005. The performance benefits of using an inerter in various systems, such as vehicle suspensions, buildings, trains, bridges, robots, and landing gears, have now been demonstrated. Inerters can also potentially be implemented in other mechanical and mechatronic systems, anticipated to influence such areas as acoustics, elastodynamic networks, elastic metamaterial design, and biometric image processing. Nowadays, the inerter has become an increasingly popular research topic due to the increasing number of applications and the associated theoretical interest.
Although much effort has been conducted on inerter research with a number of influential results obtained, there are still many challenging problems to be solved such as: the physical realizations of inerters & semi-active inerters, the physical realizations of inerter-based passive and semi-active networks, systematic ways to use inerters and semi-active inerters to design various passive, semi-active and active vibration control systems, etc. Moreover, factors such as nonlinearities, uncertainties, and possible component failures, are all contributory factors to system performance, and as such are now perceived as important issues in designing inerter-based systems.
The purpose of this special issue is to provide an opportunity for scientists, engineers, and practitioners to propose their latest theoretical and technological achievements in inerter-based systems. In particular, this special issue is devoted to papers which address the development of physical realizations, mathematical methodologies, and experimental researches for inerter-based systems, including: passive, semi-active and active control with inerters; nonlinearities of inerter-based systems; experimental verifications. Topics include, but are not limited to:
- Physical realizations of inerters, semi-active inerters, inerter-based passive, semi-active and active networks;
- Linear and nonlinear analyses and modeling for inerters, semi-active inerters, inerter-based passive, semi-active and active networks;
- Mechanical network synthesis for inerter-based vibration control systems;
- Advanced control methodologies such as robust control, adaptive control, sliding mode control, and model predictive control, for inerter-based systems;
- Application of inerters to complex structural systems including vehicles, buildings, robots, etc;
- Modeling, optimization and identification of complex structural systems by using an inerter as a standard element;
- Experimental research on inerters, semi-active inerters and inerter-based vibration systems.
