Robust sensor-fault location in instrumented building structures

https://doi.org/10.58571/CNCA.AMCA.2025.006

Resumen: This work addresses the sensor fault detection problem in accelerometers placed in building structures. Given the harsh conditions to which these measurement instruments are subjected to and the importance of having non-faulty sensors, this study investigates the use of observers for estimating accelerometer faults modeled as unknown inputs. The proposed approach employs an observer that simultaneously estimates both the internal states of the dynamic system and the unknown inputs. The observer design is based on optimization techniques within the H∞ framework, that provides robustness against external disturbances, parametric uncertainties, and measurement noise. Furthermore, the observer is capable to detect and isolate these sensors failures without affecting the estimation of the structural state. Simulation results show the effectiveness of the proposed scheme and validate the theoretical framework.
