Fault Mode Analysis and Simulation of a New-Type Nozzle Control System

In order to improve the reliability and safety of a new-type nozzle control system, the fault mode of the new-type system was investigated, and some measures were performed to ensure the system works safely. Ensuring the fault handing strategy to control system was right, the fault was simulated and the handing logic to the fault also was validated. The new-type nozzle control system was discussed. The system fault mode, solution method and fault influence were analyzed initially for the controller, communication, servo -valve, electromagnetic-valve and actuator. Moreover, a new-type nozzle fault simulation system was discussed, and the simulation of system faulty was also investigated. The validation result shows that the set fault can be detected by the new-type nozzle control system, which is done rightly.
