✦ Synopsis

A modal control approach is applied to control the vibration of homogeneous and laminated plates. The controller is designed using the linear optimal control theory. The performance of the controller designed according to a structural model of the plant based on the classical plate theory is evaluated and compared with that derived in the context of a higher order plate theory. It is found that the use of the classical plate model in the design of vibration control systems could lead to erroneous conclusions concerning the performance of the actual controlled system. The strong in#uence played by transverse shear deformation and lamination on the controlled system is clearly demonstrated and pertinent conclusions are outlined.
