Seismic signal estimation in a building-like structure using an adaptive observer

Abstract

The article focuses on the estimation of a seismic signal in a building-like structure using an adaptive observer. This algorithm allows to estimate to the behavior of the structure based on the accelation measurements, achieving the estimation of uncertain signal. Thus, an adaptive observer is proposed, which estimates both the state and unknown input. The approach is validated by simulating a two-story system using real data from a real earthquake. The results demonstrate the effectiveness of the observer in estimating the displacements in the structure and the unknown seismic signal.
