This paper proposes a new method for modeling flexible structures with distributed parameters into a reduced-order model with ramped parameters, taking into consideration both the prevention of spillover and physical correspondence at modeling points. To control the vibration of a flexible structure using modern control theory, it is necessary to make a reduced-order model of the structure, due to restrictions on control system design. The order reduction may invite the problem of unstable vibration control, called spillover, by the effect of an ignored higher-order mode. In this method, nodes of the higher-order vibration modes are selected as the modeling points to prevent spillover, because of the phenomenon of uncontrollability and unobservability. The effectiveness of this method is demonstrated by applying the vibration control to a flexible tower structure.
