Vibration Suppression And Precision Positioning Of A Piezoelectric Beam With Graded Properties

This paper focuses on the development of an active control system for simultaneous precision positioning and vibration suppression of a functionally graded piezoelectric material (FGPM) beam, using finite element 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 is based on achieving the best positioning accuracy and vibration suppression simultaneously. It is demonstrated that the FEA model with integrated controller is able to reach the desired position in a relatively small time
