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 inte-grated 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 provid-ed 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 vir-tual environment,and verify core indicators.
