摘      要：A novel real-time autonomous Interval Management System(IMS)is proposed to automate interval management,which considers the effect of wind uncertainty using the Dynamic Fuzzy Velocity Decision(DFVD)*** membership function can be generated dynamically based on the True Air Speed(TAS)limitation changes in real time and the interval criterion of the adjacent aircraft,and combined with human cognition to formulate fuzzy rules for speed adjusting *** groups of experiments were conducted during the en-route descent stage to validate the proposed IMS and DFVD performances,and to analyze the impact factors of the *** verification experimental results show that compared with actual flight status data under controllers’command,the IMS reduces the descent time by approaching 30%with favorable wind uncertainty suppression *** analysis shows that the ability improvement of DFVD is mainly affected by the boundary value of the membership ***,the dynamic generation of the velocity membership function has greater advantages than the static method in terms of safety and *** the analysis of influencing factors,we found that the interval criterion and aircraft category have no significant effect on the capability of *** a higher initial altitude scenario,the initial interval should be appropriately increased to enhance safety and efficiency during the descent *** prototype system could evolve into a realtime Flight-deck Interval Management(FIM)tool in the future.
