GMV Control algorithm for structures under recorded strong earthquakes including soil characteristics

摘要

The Generalized minimum variance (GMV) Control algorithm for structures under strong earthquakes is presented in this paper. The autoregressive moving average exogenous (ARMAX) model is derived so that the soil characteristics can be incorporated within the model and consequently in the control law. The structural response with and without introducing the soil parameters (SP) are compared. El Centro and Taft earthquakes are used to demonstrate the efficiency of the proposed control strategy. The effectiveness of GMV including SP is shown since the polynomial C(q), which incorporate the soil characteristics, define the regulation closed-loop poles.
