“…This strategy aims to reconfigure control law to depending on fault scenarios and with the given hypothesis adopted to consider a case where a single fault can be isolated and estimated. To avoid isolation and estimation tasks used often before fault compensation, Allous [1] have proposed to use a classical Luenberger observer based on ARRs calculus that gives such residues. The latter becomes then an input to the inversal BG model.…”

System reliability has become one of the major concerns on industrial systems survey in order to guarantee a system lifecycle far from malfunctions, disturbances and dangers. In this context, Fault Tolerant Control systems are involved in automation engineering issues as a remedy to system reliability troubles. Thereby, we deal in this paper with a graphical Active Fault Tolerant Control (AFTC) law that compensates actuator fault effects, guarantees desirable closed-loop performances and system resilience. This tolerant control law is based on a linear Bond Graph (BG) adaptive observer to detect and estimate failures. This control framework and the adaptive observer are designed by a graphical concept using Bond Graph tool as a useful methodology for multidisciplinary systems and which is based on structural, causal and behavioural properties. To emphasis proposed controller efficiency, an hydraulic system with two tanks is modelled and controlled with and without fault scenarios.
