Active tuned inerter-damper for smart structures and its ℋ∞ optimisation

Title Semi-active suspension with semi-active inerter and semi-active damper

This paper investigates the application of semi-active inerter in semi-active suspension. A semi-active inerter is defined as an inerter whose inertance can be adjusted within a finite bandwidth by on-line control actions. A force-tracking approach to designing semi-active suspension with a semi-active inerter and a semi-active damper is proposed, where the target active control force derived b...

Assessing the effect of nonlinearities on the performance of a tuned inerter damper

On the optimisation of a hybrid Tuned Mass Damper for impulse loading

The present paper deals with the optimisation of a hybrid Tuned Mass Damper (TMD) in reducing the transient structural response due to impulse loading. In particular, a unit impulse excitation has been assumed, acting as base displacement, which is a situation that may occur in different real applications. The proposed hybrid Tuned Mass Damper is composed of a previously optimised passive TMD a...

Semi-active H∞/LPV control for an industrial hydraulic damper

In this paper, a new control strategy is developed to improve comfort and roadholding of a ground vehicle equipped with an industrial damper. This damper can be controlled by means of a small servomechanism which adjusts the damping rate. The main controller is a linear parameter varying (LPV ) static state-feedback controller synthesized in the H∞/LPV framework to compute the required damping ...
