“…It took nearly 50 years since then, however, to obtain what might be called successful AVC, due to the level of electronic precision required to create a so-called anti-noise signal with any great fidelity. A considerable amount of work has been devoted to the development of methodologies for the design and realisation of AVC systems in various applications (Allaire et al, 1983;Choi et al, 1999;Daley et al, 2004;Firoozian and Stanway, 1988;Li et al, 2003;Mukherjee et al, 2002;Sto¨bener and Gaul, 2001). …”

“…For structures with more complex geometry, such as a car body, an analytical solution does not exist, and even a FE calculation is complicated and time intensive. As an alternative, Sto¨bener and Gaul [83] used an experimental modal analysis to extract modal parameters (eigenfrequencies, mode shapes) from measurements made on a car body. The sensors and actuators are laid out based on information about the experimental mode shapes.…”

These actuators can be driven to provide an active control of the vibrations, thus reducing greatly the magnitude of the forces exerted on the car frame at the suspension attachment points. In order to implement a robust yet effective controller, a model of a 1,4 car suspension (suspension associated to a single wheel) is derived from experimentally acquired data. The structure's modal parameters are extracted from Frequency Response data, and are used to obtain a state-space realization. The performance of controller design techniques such as LQR and Hoo is assessed through simulation using the model of the suspension .
