Abstract: This study presents design, implementation and performance testing of a predictive control system for a shake table used in earthquake simulation. The system is located in the Civil Engineering Laboratory at Andes University. The table allows to keep track on an earthquake profile expressed in horizontal displacement. However, for each case, the loads vary in terms of mass and flexibility of the structure to be tested. Therefore, it is required a strict control of these variations. Dynamic model approximate to the shake table expressed in function of transference from a strategy of identification using MATLAB® was obtained to create the design. Simulations were carried out at different seismic input and the responds of different preventing controllers designed were analyzed. Finally, the results obtained of predictive controllers operating the table under three different loads conditions are presented.
