Abstract
AbstractRecently, system functional simulation mostly uses discrete functional logic models, and it is difficult to simulate the impact of continuous behavioral parameter changes on functional logic. To remedy the addressed issue, a functional simulation method integrating a discrete functional model and continuous behavior model is proposed to help engineers analyze the correctness of functional design efficiently. Firstly, a component functional modeling and a system functional architecture modeling method are established based on state machine; secondly, a model integration simulation method based on FMI is established to integrate discrete function models and continuous behavior models of components or systems; Finally, this paper takes the aircraft elevator system as an example to verify the application of functional modeling and simulation methods. The application results show that the functional modeling and the simulation method which integrates dynamic behavior can simulate the continuous behavior and the system function execution effectively. Thereby, the engineers can ensure the correctness of the system design with this method.KeywordsFunctional modelsState machineFMISimulinkIntegrated simulation
