Abstract
In response to the challenges posed by high-density launch missions,rapid iterations,and intelligent upgrades in spacecraft test tasks,as well as the limitations of traditional spacecraft comprehensive test methods-characterized by physical test,waterfall models,and manual inter-pretation-in meeting the requirements for high reliability,high efficiency,and cost-effectiveness,an intelligent test and verification method is proposed for spacecraft using digital-physical fusion technology.Specifically,the overall design of the intelligent test and verification method focuses on two key aspects:digital-physical fusion verification and artificial intelligence(AI)empower-ment.By adhering to the principles of digital-physical consistency,temporal-spatial synchroniza-tion,and data homomorphism,a digital-physical fusion verification environment is established to achieve test frontloading.Leveraging advanced AI technologies such as large models,reinforce-ment learning,and knowledge graphs,the method constructs a full-lifecycle intelligent closed loop spanning test design,execution,interpretation,and optimization.Comprehensive test by using the digital-physical fusion technology has broken through key technologies such as integra-ted design,simulation and test for complex spacecraft,digital-physical fusion verification tech-nology,and intelligent test technology.By establishing a new paradigm for comprehensive test of spacecraft characterized by digital-physical mapping,dynamic iteration,and intelligent decision-making,this method enables the transition of spacecraft test and verification from experience-driven to data-intelligence-driven processes,thereby enhancing comprehensive test capabilities.关键词
