中文摘要:飞机飞行控制系统是典型的包含控制、电学、液压、机械等多领域的复杂系统。该文针对飞机飞行控制系统提出并实现了一套基于Modelica语言的多领域模型构建、仿真分析、代码生成的流程方法。针对某型飞机飞行控制系统基于Modelica语言进行了多领域模型统一实现,并通过试验/试飞数据对模型进行了仿真分析与验证。再通过功能模型接口(Functional Mockup Interface,简称FMI)技术将所构建的系统模型生成模型实时代码,并在工程模拟器中得到了工程验证。提出的针对系统设计建模、仿真分析、代码生成与半物理应用一体化的方法流程贴合研发过程,符合设计人员使用习惯,并充分发挥了模型在设计过程中的价值。仿真示例的分析结果以及工程模拟器试验均验证了本流程方法的有效性。
英文摘要:Aircraft flight control system is a typical complex system which includes control, electrical, hydraulic, mechanical and other fields. This paper introduces a set of multi domain modeling, simulation and code generation method based on Modelica for aircraft flight control system. Firstly, a multi domain flight control system model of a certain aircraft was implemented based on Modelica, which had been simulated and verified by experiment/flight test data. Then real time code was generated from system model through the FMI technology, which was also engineering validation in the engineering development simulator. The method of modeling, simulation, code generation and semi physical application proposed in this paper was suitable for the development process, which well met the designer’s habits and gave full play to the value of the model in the design process. Finally, the results of the simulation and the engineering development simulator test verified the effectiveness of the proposed method.
