Abstract

Increasing engineering activities in the development and industrial application of piezoelectric smart structures require effective and reliable simulation methods and design tools [2], [9], [14]. In our opinion, the finite element method (FEM) is an excellent approach to develop a tool, which meets the relevant engineering requirements. Recently, an overall simulation and design tool for piezoelectric controlled smart structures has been developed, containing both a suitable controller design and the appropriate actuator/sensor placement. To model complex engineering structures, a library of multi-field finite elements has been developed with coupled electric and mechanical degrees of freedom for 1D, 2D and 3D continua as well as for thin-walled layered structures [4].KeywordsState Space ModelSmart StructureFeedback Gain MatrixSinusoidal DisturbanceFinite Element ToolThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
