“…Considering the now vast literature in the vibration control area, there is no consensus regarding the most suitable control design method. Several techniques seem to give similar results, as shown in the works of Baz & Chen (2000); Bhattacharya et al (2002); Hurlebaus et al (2008). Linear matrix inequalities methods, due to powerful yet simple formulation and computational solution to implement the theory of robust control, present nowadays a slight predominance (Boyd et al, 1994;Zhou & Doyle, 1997).…”

“…This approach stems from the consideration that the response of a mechanical system to a disturbance is the sum of the independent responses of its vibration modes. This motivates the desire to design a controller that doesn't alter these mode forms, but allows to change independently the natural frequency and the damping associated [16,17,18]. The active control logic is designed to generate a control force that is proportional to the speed of the mode to be controlled and synchronous with it.…”

A big problem in cruise ships is related to noise and vibrations generated by engines and exhaust stacks. Reduction or control of ship noise has traditionally been implemented by passive means, such as by the use of vibration isolation mounts, flexible pipe-work, and interior acoustic absorbing materials. However, these passive noise control techniques are effective mostly for attenuating high-frequency noise, while they are generally ineffective for controlling the low-frequency one. This paper presents an active vibration control of ship bulkheads based on independent modal control technique using magnetostrictive actuators. In the first part of the research, a mock up of the vibrating bulkhead is reproduced in laboratory and a mechanical model of both the system and actuators has been realized. The modal control has then been simulated focusing on actuators and sensors position and number to improve the system's controllability and observability properties and hence allow to obtain optimal performances in terms of vibration reduction. The influence of boundary conditions has also been taken into account in order to be able to predict the control logic performances in the various possible scenarios.

“…Examples include, but are not limited to, early modal control avoiding spillover phenomena (Balas, 1978), recent modal control strategies were described and highlighted in (Inman, 2006;Singh et al, 2003), the conventional PID control (Sutton et al, 1999): input shaping (Singhose et al, 1997), minmax LQR (Petersen & Pota, 2003), modal control (Hurlebaus et al, 2008), H 2 /H  robust (Anthonis et al, 1999), distributed controller (Bhattacharya et al, 2002); time delay control (Jalili & Olgac, 1999) model predictive controller (Wills et al, 2008), nonlinear controller (Gaudiller & Matichard, 2007); and spatial H 2 and H  controllers (Halim, 2007;Halim et al, 2008;Barrault et al, 2008;Mazoni et al, 2011). This control approach allows achieving vibration control at spatial regions of interest, which may be, very useful in a DTAC system.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Abstract: Damage tolerant active control is a new research area related to fault tolerant control design methods applied to mechanical structures. It encompasses several techniques commonly used to design active vibration controllers and to detect and diagnose faults, as well to monitor structural integrity. Brief reviews of the common intersections of these areas are presented, with the purpose to clarify their interrelations and also to justify the new controller design paradigm. Some examples help to better understand the role of the new area.
