Vibration control systems

Vibration Control in Automotive Systems

In the paper, the design of a linear motor as an actuator in vehicle active suspension systems will be presented. The attention is focused on several interesting design aspects of the non-traditional actuator (linear synchronous permanent magnet motor with electronic commutation) controlled to obtain a variable mechanical force for a car damper. The main advantage of such a solution is the poss...

Active Vibration Control of Multibody Systems

Vibration Control Design for Nonlinear Systems using Frequency Response Function

A nonlinear frequency response based adaptive vibration controller is proposed for a class of nonlinear mechanical systems. In order to obtain the nonlinear Frequency Response Function (FRF), the convergence properties of the system are studied by using the convergence (contraction) theory. If the system under consideration is: 1) convergent, it directly enables to derive a nonlinear FRF for a ...

Model independent control of lightly damped noise/vibration systems.

Feedforward control is a popular strategy of active noise/vibration control. In well-damped noise/vibration systems, path transfer functions from actuators to sensors can be modeled by finite impulse response (FIR) filters with negligible errors. It is possible to implement noninvasive model independent feedforward control by a recently proposed method called orthogonal adaptation. In lightly d...

A Study of Vibration Control Systems for Superconducting Maglev Vehicles (Vibration Control of Lateral and Rolling Motions)

The superconducting magnetically levitated transport (Maglev) system is conceptualized as a next-generation high-speed transportation system. For practical use, it is important to achieve adequate ride comfort particularly in high-speed running. Maglev vehicles are composed of lightweight car bodies and relatively heavy bogies which are mounted with devices such as superconducting magnets (SCMs...
