Generalized Minimum Variance Control for MDOF Structures under Earthquake Excitation

Abstract EN

Control of a multi-degree-of-freedom structural system under earthquake excitation is investigated in this paper.

The control approach based on the Generalized Minimum Variance (GMV) algorithm is developed and presented.

Our approach is a generalization to multivariable systems of the GMV strategy designed initially for single-input-single-output (SISO) systems.

Kanai-Tajimi and Clough-Penzien models are used to generate the seismic excitations.

Those models are calculated using the specific soil parameters.

Simulation tests using a 3DOF structure are performed and show the effectiveness of the control method.
