Modeling the Use of the Patch Piezo-Actuators for Active Vibration Control

In this paper, modeling active vibration control for a thin mechanical structure as a cantilever beam with bonded piezoelectric patches is analyzed. The transversal linear force produced by a linear piezo-actuator is replaced by the moment of force produced by the patch piezo-actuator, which is glued to the surface of the thin structure. Beam deflection measurement is replaced by measuring the elongation or shortening of the surface of the deformed beam. To analyze the effect of various controllers on vibration damping, a model using Matlab Simulink is created.
