为满足复杂导弹仿真系统中不同仿真成员之间的互操作以及仿真应用可重用的要求,提高仿真系统的可维护性和扩展性,设计了基于HLA的某导弹仿真系统总体框架并开发了基于Modelica的导弹仿真模型库,开发了基于Modelica的导弹飞行轨迹控制模型仿真应用和视景仿真应用,并作为基于HLA仿真系统的联邦成员加入到了仿真联邦中,实现了基于Modelica的导弹飞行轨迹控制模型与视景仿真仿真系统以及其他仿真应用之间的交互。融合最新仿真技术的仿真应用只要符合HLA标准,就能够方便地加入到现有的仿真系统中。视景仿真应用的加入为设计人员提供了可视化的评估手段。最后,给出了导弹分飞行轨迹控制仿真和视景仿真的结果。基于Modelica的导弹模型具有高度重用性,为导弹系统中新型号导弹的开发提供了高度的灵活性。
In order to meet the requirements of interoperability among different simulation members in complex missile simulation system and the reusable requirements of simulation application, the maintainability and scalability of simulation system are improved. The overall framework of a missile simulation system based on HLA is designed and a new scheme based on Modelica The missile simulation model library based on Modelica was developed, and the simulation application and scene simulation of missile trajectory control model based on Modelica were developed. As a member of federation based on HLA simulation system, the federation was added to the simulation federation, and the model of missile trajectory control based on Modelica Visual simulation system simulation and other simulation applications. Simulations that incorporate the latest simulation technology can be easily incorporated into existing simulation systems as long as they meet HLA standards. The addition of a visual simulation application gives designers a visual assessment. Finally, the results of missile sub-flight trajectory control simulation and visual simulation are given. The Modelica-based missile model is highly reusable and provides a high degree of flexibility for the development of new types of missiles in missile systems.
