Design and Application of Flight Control Actuation System Models Based on Modelica

This paper discusses the design and application method of flight control actuation system models based Modelica. According to the physical topology layout of aircraft flight control system, the model development of flight control system is decomposed from top to bottom, and all component parts of flight control system are developed by using development tool based on Modelica language, and the tree structure model library of flight control system is set up. Based on the established model library resources, the flying control system of specific aircraft can be integrated and encapsulated in accordance with the requirements. The model verification work is made through several levels of model verification to ensure that the function of the model has reached the development requirement. The confirmed flight control system models, which can be used to analyze the influence of flight control system on different user cases of aircraft ‘flight scenes, the models also can be used in real-time simulation of human in the loop with visual virtual scene. In the upgrading plan of an engineering simulator, the flight control system models are transformed into FMU models of FMI interface standard and loading into the engineering simulator to run successfully.
