This paper considers the active vibration control of a distributed-parameter planar structure using smart cluster sensors. Difficulty in controlling the distributed parameter structure lies in an infinite number of vibration modes it has. To cope with this problem, the previous paper presented a cluster filtering approach that enables one to categorize all the structural modes into a finite number of clusters, each cluster possessing same properties in common. It is the purpose of this paper to generalize a smart cluster sensor that can deal with a generic rectangular panel with symmetrical boundary conditions. First, a design procedure of generalized smart cluster sensors is presented, thereby allowing an arbitrary placement of the sensors on a targeted panel. Next, a novel smart cluster control is shown that is capable of measuring all the structural modes and of avoiding observation/control spillover problems. Furthermore, the smart sensor output is described explicitly using the Fresnel integrals. Finally, the experiment of smart cluster control is conducted, demonstrating the validity of smart cluster control.
