“…Despite the fact that Bond Graph (BG) model is a powerful tool for the system integrated multi-energy domains, 13 only few researches use bond graph concept for EPS modeling. [14][15][16] The novel ideas of the present paper are to combine the inverse bond graph model and the fault estimation based on adaptive observer to generate the fault detection and isolation (FDI) and FTC algorithms. The major contributions of this work can be outlined as follows:…”

Electric power steering is an advanced steering system that uses an electric motor to improve steering comfort of the car. As a result, the failures in the electric motor can lead to additional fault modes and cause damage of the electric power steering system performance. Hence, to ensure the stability of this latter, the present paper proposes a new method to reconfigure the fault control. A novelty approach of fast fault estimation based on adaptive observer is also proposed. Moreover, to guarantee optimal and fast control, a fault-tolerant control based on inverse bond graph modeling is designed to construct the behavior of the nominal system. The simulation and the experimental results on a real electric power steering system reveal the importance of the control strategy and show that the proposed approach works as intended.

“…Currently there are a few researches for EPS modeling using bond-graph theory. The document [3] proposed the theory into steering system modeling without assist motor; In the document [4,5], EPS model is built without considering road random inputs and the energy coupling part is still built on the basis of classical mechanics theory, in addition, the assist characteristic and driver control model are neglected which exert an influence on the system.…”

As a tool of modeling the system of multiple energy, bond-graph theory is applied to the modeling for electric power steering system which is electromechanical hybrid. Bond graph models for C type, P type and R type of EPS dynamic system are built respectively. The CH7140 type of car equipped with C type EPS is taken as a prototype and its maneuverable performance is simulated under typical working conditions. A PID control method with time delay transfer function is adopted to imitate the driver’s operation. Steering maneuverability test of the CH7140 car is conducted. The simulation result is consistent with the test result. It is shown that the bond-graph model of EPS is rational, and simulation model derived from bond-graph is effective which can be applied to EPS and full vehicle steering maneuverability simulation research.
