Abstract
This paper presents a novel active vibration control methodology termed "active boundary control"-ABC-which enables one to generate a desired boundary condition at any designated position of a target beam structure, thereby permitting the structure to possess desired properties characterized by the boundary conditions. It is found that applying ABC to the driving point of abeam where a disturbance force acts, suppression of all the vibration modes of a flexible beam may be achieved. It is also found that applying ABC to a current conventional boundary condition of a beam, a beam, a completely vibration-free state in the designated region of a beam can be realized.
