Fault Diagnosis with Adaptive Control for Discrete Event Systems


Yamen El Touati and Mohamed Ayari


Vol. 21  No. 11  pp. 165-170


Discrete event systems interact with the external environment to decide which action plan is adequate. Some of these interactions are not predictable in the modelling phase and require consequently an adaptation of the system to the metamorphosed behavior of the environment. One of the challenging issues is to guarantee safety behavior when failures tend to derive the system from normal status. In this paper we propose a framework to combine diagnose technique with adaptive control to avoid unsafe sate an maintain the normal behavior as long as possible.
