Abstract

The active control of vibration for a beam subjected to multi-disturbances is investigated based on wave propagating suppression. In this control system, there are the same numbers of the sensors, the signal inputting to the controller and the disturbances, but there is only one controller. It is a local control system, the system parameters depend only on the characteristics of the structure bounded by the sensors and the controller, and we need not take into account the boundary conditions and the properties of structures outside of this field. The system is efficient when a structure vibrates in middle and high frequency regions. Some control design rules are developed from the calculation results.
