This paper addresses the robust (in the disturbance de-coupling sense) design problem of fault detection and isolation observers for uncertain continuous-time linear descriptor systems. In the considered set-up, the only available signal is the output variable. A bank of disturbance-decoupled filters are designed to distinguish actuator from sensor faults. A fault sensitivity analysis is discussed for three different classes of faults affecting both the actuators and the sensors.

Abstract

This paper addresses the robust (in the disturbance de-coupling sense) design problem of fault detection and isolation observers for uncertain continuous-time linear descriptor systems. In the considered set-up, the only available signal is the output variable. A bank of disturbance-decoupled filters are designed to distinguish actuator from sensor faults. A fault sensitivity analysis is discussed for three different classes of faults affecting both the actuators and the sensors.
