Simulation of a Sliding Mode Controller for a Uniaxial Seismic Shake Table

Damage to essential infrastructures has been the key reason why earthquakes are considered to be the deadliest natural hazard. Hence, it is necessary to properly simulate and test the rigidity of building designs against earthquake vibrations. Small-scale shake table tests have been developed to observe the performance of structure designs against dynamic loading that resemble a real earthquake. In a shake table, the controller serves as a key component that ensures proper movement of the loading plate to provide accurate earthquake simulation movement. In this paper, a sliding mode controller has been proposed and simulated for a uniaxial seismic shake table using MATLAB Simulink.
