摘　　要：单一的离散系统仿真或连续系统仿真已无法满足复杂的CPS系统仿真需求。结合CPS一体化模型的3类实体,对计算实体构建基于事件驱动的离散事件仿真模型(UML模型),对物理实体构建基于动态连续时间坐标的连续时间仿真模型(Simulink模型),并以刻画计算实体和物理实体的交互接口和行为特征为目的,进行协同仿真,构建交互实体模型。给出并分析了UML/Simulink协同建模的优点,研究并分析了3种不同的模型融合方法,结合无人机模型,从模型级对CPS一体化模型的融合进行了分析设计。Single discrete system simulation or continuous system simulation can＇t meet the complex needs of CPS si-mulation.We divided the integrated model of CPS into three types of entities,built discrete event simulation model（UML model） based on event-driven for the computation entity,continuous-time simulation model（Simulink model） based on time-driven for the physical entity.We applied co-simulation to construct interactive entity,characterizing the interfaces and behaviors of computation entity and physical entity.This paper introduced the advantages of the collaborative modeling of UML/Simulink,investigated and analyzed three different methods for model merging.At the model level,we designed the fusion of the CPS integrated model on the basis of unmanned aerial vehicle model.
