Bond Graph Modeling and Fault Diagnosis of Aircraft Rudder Hydraulic System

It is important to ensure that the flight control system is fault-free for the safe and reliable flight of aircraft. The hydraulic system of hydraulic rudder is the core part of the flight control system actuator. Its physical processes involve different energy domains and its failure modes are diverse. Therefore, this paper applies bond graph in aircraft rudder hydraulic system modeling and fault diagnosis, and at the end, the simulation is carried out in MATLAB/Simulink.
