Diagnosis of simultaneous sensor faults in structural health monitoring systems

Current fault diagnosis concepts in structural health monitoring (SHM) are limited by the sole consideration of single sensor faults, which does not fully capture complexity real-world faults SHM systems. This paper presents an adaptive approach for systems that addresses multiple simultaneously. The approach, based on analytical redundancy, includes detection, isolation, and accommodation, has been validated using data recorded from a railway bridge. results show high accuracy, reliability, performance proposed regarding occur simultaneously
