Fault Diagnosis by Bond Graph Functional Observer


Attafi Rim and Zanzouri Nadia


Vol. 18  No. 11  pp. 32-41


A diagnosis by functional observers based on bond graph approach is proposed in this paper. Taking into account its structural and causal properties, the bond graph model is used for modeling, residual generation and simulation purposes. The paper also highlights and clarifies the need for the optimization method as LMI (Linear Matrix Inequality), to outline the stability performances. Simulation results on the stringing machine are provided to show the dynamic behavior of system variables and to evaluate the performance of the observer for diagnosis tasks.
