Robust Fault Detection of Smart Structure Control Systems with Model Uncertainty

Abstract

This paper proposes a method of model-based fault detection that is insensitive to the uncertainties due to unknown parameter errors whereas it is highly sensitive to the component failures. The proposed method is applied to the sensor failure detection of a smart structure control system and numerical simulation results show that the present approach is effective in suppressing disturbances due to model uncertainties and remarkably improves the detection performance.
