This paper investigates the control of flexible structures using direct output feedback. Most papers published on structural control assume that all the system states are available for measurement; see for instance, [1,2,3], to just name a few. In practice, only a limited number of measurement sensors will be deployed in the system. Especially, when the degree of freedom of the problem gets larger; which is always the case when dealing with civil structural models, implementation of full state feedback control becomes difficult if not impossible. A direct output feedback control, on the other hand, uses information that is directly measured through sensors. One may want to consult [4,5] for references. In this preliminary study, we only consider systems with single-input and single-output. A numerical simulation shows the effectiveness of the proposed direct output feedback.
