Failure detection, identification and accommodation based on a new accommodation filter

Abstract

This note is a comment on the paper of B. C. Moon and Z. Bien (Failure detection, identification and accommodation based on a new accommodation filter) 1991, Int. J. Systems Sci., 22, 1025. The authors give an original formulation of the problem of failure detection of sensors and actuators based on a state reconstruction via observers. In this response, we follow the proposed method which is simplified and compared to a more direct approach.
