Research project: Active vibration control of parametrically excited systems.

Currently Active: 
Yes

EPSRC First Grant (Ref: EP/K005456/1). This project considers active vibration control of parametrically excited systems (PES). The problem is to develop control strategies for the suppression, or enhancement, of parametric resonances in engineering systems.

Project Overview

This project considers active vibration control of parametrically excited systems (PES). The problem is to develop control strategies for the suppression, or enhancement, of parametric resonances in engineering systems. Active control has the potential to control large amplitudes of vibration and modify the dynamics of the system very efficiently. It is particularly suitable for PES since the dynamics of PES are periodic-time dependent.

Many engineering structures are subjected to parametric excitation, which is produced by some external loads interacting with the structure. Parametric resonances can occur in cable-stayed bridges, in aeroplane wings, in flexible risers and in ships.
