摘要

针对飞控系统设计面临的各种问题,研究了一种基于图形化建模语言、支持模型驱动开发的飞控系统数字样机设计技术.基于Rhapsody,STATEMATE,Simulink等搭建了用于飞控系统数字样机设计的支撑平台,研究了基于支撑平台的飞控系统数字样机设计流程及数字样机的四个不同侧面;以一小型无人机飞控系统为例,详细介绍了其数字样机设计,并进行了两个层次的检查和仿真验证.设计实践表明该方法能有效缩短设计时间,提高设计质量,支持后期软件的模型驱动开发,适用于各类飞行器控制系统数字样机的设计.%Aiming at problems in flight control system design, the Flight Control System Digital Prototype (FCSDP) design technology based on graphical modeling languages was studied, which could support Model Driven Develop ment (MDD). Firstly, supporting platform based on Rhapsody, STATEMATE and Simulink etc. was constructed.And the design process and four profiles of FCSDP were studied. Then, taking an unmanned aerial vehicle flight control system for example, its digital prototype design was described in detail, and the verification and simulation were conducted. Design practice revealed that the method could shorten design cycle, improve design quality, support flight control software MDD effectively. It was suitable for various aircraft FCS design.
