BERNAL, Mauricio; APONTE, Jorge  e  CARRILLO, Julián. Control systems for shake tables: A critical review. Ing. Desarro. [online]. 2015, vol.33, n.2, pp.331-355. ISSN 0122-3461.

Shake tables are crucial tools for studying the performance of structures under seismic actions. These devices have become an essential tool for earthquake-resistant engineering and have demonstrated to be effective for studying complex structural dynamic models. One of the most important aspects to consider during implementation of a shake table is the system control needed to reproduce accurately the seismic movements. From an extensive revision of available literature, this article examines and discusses some of the controls more used in different types of shake tables around the world. Based on the analysis of scopes, advantages and drawbacks of control systems studied, it is also indicated the controls having great feasibility to be implemented in shake tables of single and multiple degrees of freedom.

Palavras-chave : automatic control; classic control; dynamic test; modern control; robust control; shake table.
