This paper describes a vibration modeling procedure for an arbitrarily shaped elastic structure using FEM. Based on this model, a method of controlling the system in which a sensor is not collocated with an actuator is also investigated. In this procedure, the controlled modes can be selected by taking the transient response amplitudes of each mode into account. A motion and an observation equation are derived employing these controlled modes as state variables, and the control law is determined using an optimum control theory. The influence of residual modes such as spillover on the control system is illustrated by numerical studies on the feedback control of an elastic rectangular plate. Based on these results, modeling criteria are obtained for reducing the effect of spillover.
