Study on active vibration control technique based on cantilever beam
In order to solve the contradiction between lightweight and noise of a vibrating cantilever beam, active control actuated by piezoelectric ceramics is presented in this study. The dynamic model of the cantilever beam is established by finite element method (FEM). The piezoelectric actuator excited by control signal is bonded near the fixed end of the cantilever beam to suppress the beams first vibration mode. The control signal is collected by a sensor and processed by the quadratic optimal control theory. Experiment results show that the amplitude of the active controlled cantilever beam is reduced to 48.2％ than the uncontrolled one under constant external excitation.
