Direct Output Feedback Control of Flexible Structures
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.
