| 摘要:针对船舶混合动力推进系统能量管理策略的复杂验证需求,设计一种基于NI PXIe双实时仿真机的分布式数字化验证平台。该平台采用分布式分层架构设计,将混合动力推进系统多物理场模型(部署于下层实时仿真机)与能量管理策略模型(部署于上层实时仿真机)解耦,通过高实时性CAN通信实现微秒级同步交互,构建闭环验证环境。平台支持多能源协同优化、动态工况切换及故障注入等场景测试,平台实现模型分布式交互延迟<50 μs、动态工况切换误差<2%,显著提升了策略的工程可信度。相较于传统单机验证,其模型-策略分布式解耦架构解决了模型耦合度高、硬件扩展性差的问题,验证效率提升40%。为跨物理域协同控制与多目标优化策略开发提供了标准化工具链。该平台兼具高动态响应与虚实融合验证能力,对船舶及其他高动态混合动力推进系统的数字化验证具有普适参考价值。 |

| Abstract:A distributed digital verification platform based on NI PXIe dual real-time simulation machine was designed to meet the complex verification requirements of energy management strategies for ship hybrid propulsion systems.The platform adopts a distributed layered architecture design,decoupling the multi physics field model of the hybrid propulsion system (deployed on the lower real-time simulation machine)from the energy management strategy model (deployed on the upper real-time simulation machine),achieves microsecond level synchronous interaction through high real-time CAN communication,and constructs a closed-loop verification environment.The platform supports scenario testing such as multi energy collaborative optimization,dynamic operating condition switching,and fault injection. The platform achieves a distributed interaction delay of less than 50 μs and a dynamic operating condition switching error of less than 2%,significantly improves the engineering credibility of the strategy.Compared to traditional standalone verification,its mode-policy distributed decoupling architecture solves the problems of high model coupling and poor hardware scalability,improves verification efficiency by 40% and provides a standardized tool chain for cross physical domain collaborative control and multi-objective optimization strategy development.This platform combines high dynamic response and virtual real fusion verification capabilities,and has universal reference value for the digital verification of ships and other high dynamic hybrid propulsion systems. |
