At the early stage of the population evolution, an adaptive hierarchical retention strategy is applied to replace the exclusion mechanism to get an expanded range of individuals selection and improve the diversity of the population. At the last stage of the population evolution, an interval population expansion strategy is provided to expand the contemporary optimal frontier individuals to reduce the sparsity of the swarm distribution aiming to improve the comprehensive performance of the population. The experiment results based on six selected benchmark functions show that the proposed algorithm gets a better convergence and is superior to the compared algorithms in the terms of comprehensive and distribution values.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"45 1","pages":"2269-2273"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78527657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through calculation and analysis, it is found that the use rate of the existing station air compressor can be reduced by using gas turbine for compressed air in station, but the performance of gas turbine will be affected to a certain extent. Compared with the existing air compressor energy consumption, it does not have an advantage in economy. However, the influence of the maintenance, spare parts procurement, power supply and technical blockade of the existing electric drive air compressor in the existing station can be comprehensively considered, and the technical transformation can be carried out according to the situation.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"65 1","pages":"563-573"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77029130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a large aircraft real-time flight trajectory management strategy based on 4D trajectory under multi-constraint conditions. To improve the prediction accuracy of the feasible Controlled Time of Arrival (CTA) window, a calculation method based on aircraft performance data and aircraft intention model is proposed. Finally, a dynamic en-route speed adjustment strategy based on the aircraft kinematics model is proposed, and the optimal flight profile and the required time of arrival objectives of the CDO are achieved with the performance-based airspace and CTA procedures. To demonstrate the validation of the algorithms given in the paper, the fast-time simulation based on a type of domestically-made aircraft is operated by the MATLAB platform. The simulation results verified that the real-time trajectory management algorithms and dynamic en-route speed profile adjustment strategy proposed in this paper could provide a precise flight speed control capability oriented to timing arrival for airlines.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"25 1","pages":"422-427"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87134767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
