Flight Control System Conceptual Prototype Design Based on SysML and Simulink

A flight control system conceptual prototype design method based on integration of SysML and Simulink is researched.Firstly,the improvements between SysML and UML /STATEMATE that meet the flight control system design requirements are introduced.Secondly,a SysML extension mechanism that integrates SysML and Simulink model through code embedding is researched,the key problems it faces are analyzed and its profile definition is given.In the last,taking an unmanned aircraft system for example,the conceptual virtual prototype of its flight control system predator is designed,and functions,behaviors of predator are verified and validated.The design practice shows this method could meet the design requirements of flight control system conceptual prototype.
