　　Distributed structures are infinite-dimensional.It is impossible to control or estimate the entire infinity of modes.The vibration control of such a structure is limited to a finite number of modes.Both observation and control spillover problems thus arise due to the modal truncation[1, 2].In reference [3].the feedback wave controller is adopted to reduce the resonant response of high frequency residual modes, thereby reduce the effects of control spillover.
