Actuator fault detection using a bond graph approach

This paper deals with Actuator Fault Diagnosis using multi energy Bond Graph approach. Namely, it is shown how the structural properties (monitorability) and the fault signatures can be deduced directly from multi energy bond graph models (well adapted for process engineering modeling) with no need for any calculation. This approach is applied to a part of a pilot power station in order to analyse the monitorability of the actuators considered in bond graph methodology as control sources.
