Abstract

In this paper we present three new schemes for sensor and actuator fault diagnosis for linear time-invariant systems: multirate parity-space techniques, multirate observers, and multirate detection filters. We show that these approaches offer distinct advantages over conventional fault diagnosis schemes in terms of ease of failure detection, the speed and the class of systems for which detection is possible. There are two primary contributions in this paper. First, we develop schemes for system-wide fault diagnosis, as compared with single component fault detection and isolation. Secondly, we show that the diagnosis of single faults is a generic system property.
