RODRIGUEZ-CASTRO, Ramón; ALCARAZ-CARACHEO, Alejandro  e  SANCHEZ-RODRIGUEZ, Álvaro. Numerical modal control of a flexible beam structure. Ing. invest. y tecnol. [online]. 2018, vol.19, n.2, pp.125-134. ISSN 2594-0732.  https://doi.org/10.22201/fi.25940732e.2018.19n2.011.

A pole placement method was applied in feedback numerical control of an intelligent flexible beam. Finite element techniques were used for the discretization of the continuous beam and from the corresponding state space representation, control gains were obtained by the pole allocation method for the appropriated modal control. The results obtained from numerical simulation show that control of the first three vibration modes is efficiently accomplished with a single input control.

Palavras-chave : Modal structural control; smart flexible structure; pole allocation; single input control; active control.
