研究了一种基于SysML与Simulink的飞控系统概念样机设计方法。首先分析了SysML相对于UML的扩展及其比STATEMATE/UML更适合飞控系统概念样机设计的原因;其次,为了实现对飞控系统概念样机设计过程的完整支持,研究了一种实现SysML与Simulink模型集成及协同仿真的SysML扩展机制,分析了扩展机制需要解决的关键问题以及扩展机制的Profile定义;最后,以一无人飞行器飞控系统Predator为例,基于SysML与Simulink对其概念样机进行了设计,并进行了仿真验证。设计实践表明该方法能有效支持飞控系统概念样机设计。
A prototype design method of flight control system based on SysML and Simulink is studied. First of all, the reason why SysML is extended relative to UML and its concept prototype is more suitable than that of STATEMATE / UML is also analyzed.Secondly, in order to realize the full support of the conceptual prototype design of flight control system, a method to realize SysML and Simulink Model integration and co-simulation. The key problems to be solved and the definition of the extended mechanism are analyzed. Finally, a UAV flight control system, Predator, is taken as an example. Based on SysML and Simulink, the concept prototype is implemented Design, and simulation verification. Design practice shows that this method can effectively support the concept of flight control system prototype design.
