Abstract

In this work, two control strategies are compared in an earthquake engineering context: Proportional-Integral-Derivative Control (PID) and Model Predictive Control (MPC). A comprehensive overview of these techniques is presented and a comparison using an academic second-order system is detailed. The differences between both trategies are illustrated considering their performance in earthquake-engineering-type applications. It is therefore concluded that MPC is preferred to control complex nonlinear systems, whereas PID is suited to regulate more simple dynamical processes. Aiming to achieve a more realistic comparison, the hydraulic actuators of the shaking-table have been controlled with PID and MPC to reproduce seismic signals. The model of the piston was provided by CEA-EMSI laboratory, showing once again that the computational complexity of MPC allows more accurate correcting actions than PID.
