| Research Abstract |
The objective of this study is to expand the conventional active wave control for a flexible panel to the case of an orthotropic panel. First, this study began with describing the dynamics of an orthotropic rectangular panel using a transfer matrix method. It was found that when a rectangular panel has orthotropy, the structure has two cut-on frequencies. Then, active wave control for such a structure was systematically established from a viewpoint of feedforward and feedback techniques.
