基于SCADE的自动飞行控制系统设计与仿真

摘要

飞机飞行的安全性是航空业发展的重要课题，自动飞行控制是降低驾驶员工作负荷，提高飞行安全性的有效途径。利用高安全性应用开发环境SCADE，综合考虑飞机运动安全特性，通过数据流程图，平面状态以及安全状态机的建模方法，建立了飞机俯仰方向的自动飞行控制系统的模型。通过飞机仪表盘可视化以及襟翼状态仿真界面，利用验证模块，飞行数据测试等手段，完成了模型的可靠性验证并利用SCAD-KCG生成满足DO-178B民航A级标准的高可靠性嵌入式实时C语言代码。%Aircraft flight safety is an important topic in the aviation industry development, the automatic flight control is the effective way to reduce pilot workload and improve flight safety.Considering the aircraft movement security features,automatic pitchingflight control system model is set up in a high security SCADE application development environment by the data flow diagram,surface state and safety state machine modeling method.Through designing the dashboard and flap state simulation interface,the reliability of the model validation is completed by using the authentication module and data test.A high reliability embedded real-time C language code which meets the DO-178B grade A standard of civil aviation is generated by SCADE-KCG.
