Research on Joint Simulation Method of Heterogeneous UAV Model Based on FMI Standard

针对无人机设计阶段各子系统模型复杂度不同、建模工具不同导致难以开展联合仿真的问题,提出了一种基于FMI标准(Functional MockupInterface,FMI)的飞行器异构模型联合仿真方法。以某无人机的飞行动力学模型和发动机模型为例,生成各子系统的FMI接口模型,采用MatLab Simulink软件实现子系统模型联合集成与调用,有效提高了异构模型联合仿真效率,研究结果可为无人机联合仿真的工程实践提供参考。

Aiming to the issue of difficulty in carrying out joint simulation resulting from different degree of complexity of models and different modeling tools for each subsystem at UAV design stage.This paper puts forward a kind of joint simulation method of air vehicle heterogeneous model based on FMI(Functional MockupInterface)standard.By taking the model of the flight dynamics and engine model of a certain type of UAV,FMI interface models for all subsystems are generated and MatLab Simulink software is adopted to achieve joint integration and transfer of subsystem models so that the efficiency of joint simulation of heterogeneous model is effectively improved.The research result can be referred to for engineering practice of UAV joint simulation.
