飞控系统虚拟设计环境

开展面向设计的飞控系统虚拟原型机开发环境研究,提出了飞控系统虚拟设计环境的3层次结构:第1层为运行管理层,以数据库为基础,其核心为PDM(产品数据管理)软件.第2层为虚拟技术层,提供余度飞控计算机、舵回路、传感器等的虚拟原型的生成.第3层为仿真支持层,支持人在回路的仿真验证.分析了实现每层功能的关键技术,并基于该虚拟设计环境,完成了虚拟四余度飞控计算机的设计和验证,使该开发环境具有面向主要结构参数、性能参数、价格参数的虚拟余度飞控计算机系统生成功能.

Virtual design environments of flight control system

Design-oriented virtual design environment of flight control system was established.The virtual design environment had a three-level structure.The top level was operations management based on database technology,in which product data management(PDM) systems were used to manage design documents,product configurations,workflow and design process of virtual prototype(VP).The middle level was VP technology in which VP of redundant flight control computers,sensors and actuators were provided.The bottom level was environments supporting for man-in-the-loop simulation of flight control systems.The key technology was analyzed to realize the function of each level.The parameters of virtual prototype of redundant flight control computers(RFCC-VP) were discussed.With different parameters,architecture and performance of RFCC-VP were different.Design processes of RFCC-VP were the processes to determinate the parameters of RFCC-VP.Validation of RFCC-VP was accomplished in the environments,and RFCC-VP can be built according to its major parameters such as architecture,performance and price.
