Virtual Prototype Design Environments of Flight Control System Based on Rhapsody

为支持飞行控制系统虚拟样机设计,克服物理样机制造周期长、代价高、效率低的缺点,研究了飞行控制系统虚拟样机设计环境体系结构,集成Rhapsody,Matlab/Simulink,VC++,Doors和Oracle5个商业软件,设计了4层次结构的飞行控制系统虚拟样机设计环境,分别为元素模型设计层、虚拟部件设计层、虚拟样机集成层和调度管理层。另外,基于构建的设计环境设计了某微型飞行器的飞控系统虚拟样机,并对设计模型进行协同仿真验证。设计结果表明,该设计环境能够支持不同粒度的飞控系统虚拟样机设计,提高了飞控系统设计效率,支持各类飞行器控制系统虚拟样机的设计。

In order to support virtual prototype of flight control system(FCS-VP) design,to shorten the design period and reduce the cost of flight control system incurred by five commercial software,such as physical prototype,integrated Rhapsody,Matlab/Simulink,VC++,Doors,and Oracle,the virtual prototype design environments of flight control system(FCS-VPDE) is researched.FCS-VPDE contains four-layer: model design layer,virtual component design layer,virtual prototype integration layer and scheduling management layer.In order to test the performance of FCS-VPDE,a Micro air vehicle’s FCS-VP is designed,and co-simulation is conducted for the FCS-VP.The experimental results demonstrate that FCSVPDE is suitable for different particle size of the FCS-VP design,which can improve the efficiency of the flight control system design and support various aircraft FCS-VP design.
