Nonlinear vibration control of a flat plate structure using multiple piezoelectric devices

In this paper, piezoelectric elements are used to vibration control of a flat plate structure. In order to control vibration more effectively, we propose to divide three piezoelectric actuators into two groups to control the vibration. In details, after describing a mathematical model of the flat plate structure, an operator-based nonlinear control system is designed for the vibration of the trapezoid plate structure. The effectiveness of the proposed method is shown by evaluating the control effect using the coupled analysis tool ANSYS and then comparing the vibration control using two groups of piezoelectric actuators with the previous method by simulation.
