深空探测自主运行的一种可信性技术体系OA北大核心CSTPCD

The"unrecognized and uncertain"is the basic feature of deep space exploration missions.A technology system of dependability for autonomous operation in deep space exploration was proposed based on the principle of"scientific value maximization"-oriented exploration and reliability as the core technology.The concept of reliability in the scenario of deep space exploration was analyzed and in-volved.A dependability systematic framework for autonomous operation of deep space exploration and its overall technical architecture of"demand-cognition-engineering"were proposed,which include pre-cise sensing,optimal calculation,accurate decision-making and"quickly,precisely,exactly"execution.The reliability-oriented multi-physics deeply coupled white-box modeling and its high-fidelity technology,the complex network fault propagation mechanism and its high-confidence technology,the high-reliabili-ty assurance route for the application of COTS components in deep space exploration,the fusion mecha-nism of"model+data+knowledge"and its dynamic evolution technology for multi-agent health state management based on multiple fetal sensing phenomena were studied.The key technology of this techni-cal system and the application verification of its minimum system in the satellite constellation were in-troduced,and the results show that the technology system proposed has high engineering value.
