概要

This paper describes a method of stopping the vibration of an arbitrary point on a structure set in vibration by a disturbing force by applying an additional controlling force to it. A theoretical procedure to derive the controlling force is described for the case where the equation of motion of the structure is known and the disturbance is a known of an unknown sinusoidal or random force. The procedure for the case where the equation of motion is unknown is also discussed. A method of designing a digital filter to realize the transfer function necessary for control is shown. Experiments are conducted to test the theory using a beam simply supported at both ends by exciters, thereby subjecting the beam to the disturbing force at one end and to the controlling force at the other end. The purpose of control is well achieved for both sinusoidal and random disturbances.
