GMV control algorithm for civil engineering structures under bidirectional earthquakes using decentralized model

The Generalized minimum variance (GMV) Control algorithm for structures under strong bidirectional earthquakes using a decentralized model is presented in this paper. The structural model is derived based on a Single-Degree-Of-Freedom (SDOF) structure under two seismic waves in the x direction and the y direction. The autoregressive moving average exogenous (ARMAX) model is derived by neglecting the coupling terms between the two displacement axes and considering them as an external perturbation. The bidirectional El Centro earthquake is used to demonstrate the efficiency of the proposed control strategy. The simulation results show the efficiency of the decentralized approach based GMV control strategy.
