Abstract: The Macro Fiber Composite (MFC) is the leading
low-profile actuator or sensor offering high performance, durability and
flexibility in a cost competitive device. As an ideal candidate of
active-control devices, its application, however, is restricted by the
complicated electromechanical characteristics, and also restricted by the
unavoidable time delay lying in the MFC's actuated systems. Given this, this
paper attempts to design a GA-based controller for mitigating clamped-free
beam actuated by the MFC patches, in which these two factors are both
considered. Finally numerical examples and corresponding experimental cases
are used to testify the proposed approach is effective in mitigating
vibration with different time delays. Also recommended are the implications
of the current study on vibration control for other smart structures.
Keywords: MFC, vibration control, GA controller, time delay, clamped-free beam
