Abstract
A new method of adaptive Luenberger observer design used on actuator fault detection and estimation is investigated. This approach is based on Bond Graph representation which is a multidisciplinary tool characterised by its causal, behavioral and structural properties for control and diagnosis analysis. Thus, the necessary existence conditions are taking in consideration. An hydraulic system with two backs is considered to ensure the efficiency of the proposed graphical observer.
