Research On Model-based Systematic Design Of Flight Control System

Aimed at realizing digital design of flight control system,this paper researches the technology ofthe systematic design of flight control system employed the method of model based systemengineering, main tasks include:①It introduces the research background and points out the traditional flight control systemdesign method’s general problems such as low quality,long cycle,cost, and then puts forward themethod of model based system engineering to design the flight control system, finally this papersummarizes the current domestic and foreign model based system engineering method, and theresearch status of flight control system systematic design technology.②It introduces the method of model based system engineering, analyzes the system modelinglanguage, and then studies the scheme that carried on model based system engineering method on thesystematic design of flight control system, and discusses in detail each component part of thesystematic design and implementation technology, finally summarizes the flight control system designenvironment.③Flight control logic modeling method is researched. Firstly it in-depth analysis andcompares logical modeling tools, and then studies the modeling method based on SysML state, finallytakes sample of unmanned aerial vehicle (uav) to model the typical flight control modal logic.④The modeling method of redundancy management algorithm is studied. First it analyzes thecharacteristics of redundancy management modeling tools, and then researches the modeling methodbased on SysML activity, finally typical redundancy management algorithm model is established.⑤It further studies the flight control system systematic design environment’s modelintegration method of SysML model and Simulink model, through the analysis of architecture and callprinciple between two different models, proposes interface scheme based on code integration andshared memory, and designs a SysML with Simulink model integrated interface, realizes thesimulation of flight control system, verifies the typical flight control modal logic and redundancymanagement algorithm modeling method.
