摘要
基于系统工程建模语言(SysML)与高层体系架构(HLA),提出了一种面向复杂系统虚拟样机(VPCS)的开放式协同仿真建模新方法。该方法可以实现VPCS中各类学科异构模型的集成和协同仿真。将VPCS划分为顶层模型、联邦模型和领域组件模型,并分析了VPCS的模型调度机制;利用该方法,对某型无人机的飞控系统虚拟样机进行协同仿真建模,结果充分表明,该方法可以有效地进行多层次、多粒度、多领域的VPCS仿真建模。
Based on the system model language and high level architecture, a new approach of openended collaborative modeling and simulating is proposed for virtual prototype of complex systems. The new approach has the advantage of multidiscipline models integration and co-simulation in VPCS. In this approach, VPCS is divided into top model, federation model, and field component model. The scheduling mechanism of VPCS is analyzed. A virtual prototype of the flight control system of an unmanned aerial vehicle is carried out with the proposed approach. The simulation results demonstrate that the new approach can be effectively and efficiently used for modeling and simulation of multi-level, multi-granularity and multi-field VPCS.
