Vibration Attenuation of a Functionally Graded PiezoelectricBeam

This paper focuses on the development of an active control system for simultaneous precision positioningand vibration attenuation of a functionally graded piezoelectric material (FGPM) beam, using finiteelement analysis (FEA). The developed environment includes three modules: structural modelling,controller design, and dynamic analysis of the smart structure. The gain selection for the controller isbased on achieving the best positioning accuracy and vibration attenuation simultaneously. It isdemonstrated that the FEA model with integrated controller is able to reach the desired position in arelatively small time.
