作为一种混合系统,鱼雷是连续系统和离散系统的结合体。而鱼雷仿真贯穿于包括需求分析、设计、效能评估、模拟训练的全生命周期。针对以往仿真开发过程中缺乏共同认可的知识,提出了一种改进的混合DEVS形式化建模方法并定义了混合原子模型和混合耦合模型,在此基础上给出了鱼雷各原子模型和耦合模型的描述。构建了基于混合DEVS的鱼雷仿真本体,其顶层实体包括仿真对象、仿真序列、仿真算法、模型类、函数、参数、时间、状态、事件和仿真记录。以空投鱼雷为例,通过参照鱼雷仿真本体改造了传统的仿真模型。仿真结果表明所建立的本体能有效表示鱼雷仿真领域知识和正确指导其模型开发。
As a hybrid system, torpedoes are a combination of continuous and discrete systems. The torpedo simulation runs through the entire life cycle including requirements analysis, design, performance evaluation, simulation training. Aiming at the lack of common recognition knowledge in the process of previous simulation development, an improved hybrid DEVS formal modeling method and a hybrid atomic model and hybrid coupling model are proposed. Based on this, the atomic model and coupling model description of. The torpedo simulation body based on hybrid DEVS is constructed. The top entities include simulation objects, simulation sequences, simulation algorithms, model classes, functions, parameters, time, status, events and simulation records. Taking the empty cast torpedo as an example, the traditional simulation model is modified by referring to the torpedo simulation body. Simulation results show that the built ontology can effectively represent the field of torpedo simulation and correctly guide its model development.
