Vibration Control of a Flexible Smart Beam
Li Yong
Abstract：In this paper,the vibration control of a flexible cantilevered beam with collocated piezoelectric sensor and actuator is studied. A dynamic governing equation of motion for the smart beam is derived and a linear feedback control law is presented. By using LaSall's invariant principle in infinite dimensional space and linear semigroup theory,it is shown that implementation of the control results in vibration suppression provided that the distribution of the collocated sensor and actuator make the stabilizable condition hold.
