| 摘要: |
| 针对数字工程中异构模型集成仿真的问题，提出了一种基于狄拉克符号的系统建模方法。该方法可以屏蔽子系统的建模逻辑和模型实现差异，描述全系统的集成模型和动力学演化。利用类TNEA中间件提供的状态定义和方法调用机制，可以将异构模型映射为具有相同建模逻辑和软件接口的对象模型，构成数字主线，开展虚实融合系统集成试验。该方法可以支撑航天“簇”演进模式下的新技术快速插入、新系统原位替代和新状态快速验证，并针对数字航天开展全要素虚实融合试验，在虚拟环境中摸边探底，验证核心指标。 |

| Abstract: |
| This article proposes a system modeling method based on Dirac notation for the integrated simulation of heterogeneous models in digital engineering. This method can mask the differences of sub-system modeling logic and implementation, and describe the integrated system model and dynamic evolution. Using the state definition and method invocation mechanism provided by the TNEA-like middleware, heterogeneous models can be mapped to object models with the same modeling logic and software interface, forming the digital thread, and conducting integrated testing of virtual-real systems. It can support the cluster evolution mode of new technologies being quickly inserted, new systems being in-situ replaced, and new states being quickly verified for aerospace. It can conduct full-element virtual-real fusion tests on digital aerospace, explore the boundaries in the virtual environment, and verify core indicators. |
