predictive control with dynamic hysteresis ‎reference ‎trajectory: application to a structural base-‎isolation ‎model

Over the last decades, in the field of control engineering, model predictive control (mpc) has been successfully ‎employed in many industrial processes. this due to, among other aspects, its capability to include constrains within ‎the design control formulation and also its ability to perform online optimization. for instance, in the civil ‎engineering field, different mpc approaches have been well developed to formulate active control algorithms able ‎to reduce civil structural responses to earthquakes. thus, in this paper, a customized version of a conventional ‎predictive control (pc) strategy is proposed to mitigate the displacement on a base-isolated system with a ‎nonlinear hysteresis behavior, that is excited by a seismic event. the proposal consists of including a dynamic ‎hysteresis system into the control scheme to generate a reference trajectory that will softly drive the base-isolated ‎structure to a rest status. the proposed control scheme is evaluated through numerical experiments, and then its ‎performance is compared with respect to the conventional predictive control methodology. according to the ‎numerical experiments, the approach here presented results more efficient than the conventional method due to ‎the use of a suitable linear model of the structural system plus a new driver block with dynamic hysteresis within ‎the predictive control scheme‎.
