| 1 | Characteristic model-based all-coefficient adaptive control for automatic train control systems显示文摘Safe and reliable automatic train control is a primary consideration for any advanced rail transit system.This paper introduces the characteristic model-based modeling method into ATC system and develops an all-coefficient adaptive control.Two characteristic models,namely speed characteristic model and position characteristic model,are established for analyzing both train traction and cruising dynamical characteristics.Control strategies are proposed using single speed feedback and speed/position bi-feedback.Numerical simulations are carried out to verify the effectiveness of the proposed strategies,showing that control objective and required dynamic performance are well satisfied.Moreover,the system shows robustness against time-varying model uncertainties and unknown operational environment dynamics. | GAO ShiGen DONG HaiRong NING Bin | 2014 | Science China(Information Sciences)2014，57，9： | 8 |
| 2 | Distributed cooperative control of multiple high-speed trains under a moving block system by nonlinear mapping-based feedback显示文摘Although the high-speed railways in China have been greatly advanced in the past decades with respect to expanding networks and increasing speed, a fixed block system, which separates the trains with several stationary track block sections, is utilized to guarantee the safe operation of multiple trains. A moving block system, which enables the moving authority of a high-speed train to be the real-time positioning point of its preceding one(plus some necessary safe redundant distance, of course), is under development to further make full use of the high-speed railway lines and improve the automation level by automatic train operation for high-speed trains. The aim of this paper is to design a distributed cooperative control for high-speed trains under a moving block system by giving a cooperative model with a back-fence communication topology. A nonlinear mapping-based feedback control method together with a rigorous mathematic proof for the global stability and ultimate bound of the closed-loop control systems is proposed. Comparative results are given to demonstrate the effectiveness and advantages of the proposed method. | Bin NING Hairong DONG Shigen GAO Tao TANG Wei ZHENG | 2018 | Science China(Information Sciences)2018，61，12： | 8 |
| 3 | High-Speed Trains Automatic Operation with Protection Constraints: A Resilient Nonlinear Gain-based Feedback Control Approach显示文摘This paper addresses the control design for automatic train operation of high-speed trains with protection constraints.A new resilient nonlinear gain-based feedback control approach is proposed,which is capable of guaranteeing,under some proper non-restrictive initial conditions,the protection constraints control raised by the distance-to-go(moving authority)curve and automatic train protection in practice.A new hyperbolic tangent function-based model is presented to mimic the whole operation process of high-speed trains.The proposed feedback control methods are easily implementable and computationally inexpensive because the presence of only two feedback gains guarantee satisfactory tracking performance and closed-loop stability,no adaptations of unknown parameters,function approximation of unknown nonlinearities,and attenuation of external disturbances in the proposed control strategies.Finally,rigorous proofs and comparative simulation results are given to demonstrate the effectiveness of the proposed approaches. | Shigen Gao Yuhan Hou Hairong Dong Sebastian Stichel Bin Ning | 2019 | IEEE/CAA Journal of Automatica Sinica2019，6，4： | 2 |
| 4 | Identification and histopathological and pathogenicity analysis of Aeromonas salmonicida salmonicida from goldfish (Carassius auratus) in North China显示文摘In this study,bacterial pathogens were isolated from the liver,spleen,kidney,heart,and muscle of diseased goldfish(Carassius auratus)after a massive outbreak of disease in an aquaculture farm in Anshan,Liaoning Province,North China(N41°05′58.42″E122°53′31.89″).Based on physiological and biochemical characterization of the bacteria and 16S rDNA sequence analysis,the bacterial isolates were identified as Aeromonas salmonicida salmonicida.Virulence gene multilocus sequence typing analysis showed that the bacterial isolates from all the organs collected were of the same type,and clustered in the same phylogenetic group as A.salmonicida salmonicida.The pathogen,was named AS.17 and was resistant to rifampicin,bacitracin,vancomycin,penicillin and compound sulfamethoxazole,but was highly sensitive to nalidixic acid,lomefloxacin,spectinomycin,ofloxacin,and ciprofloxacin.Goldfish experimentally infected with AS.17 had similar symptoms to naturally infected fish,including gill filament anemia,intestinal bleeding,intra-abdominal fluid,and jaw bleeding.Histological analyses showed that the liver,the spleen,the kidney and the intestines of fish infected with AS.17 had severe pathological alterations.In summary,this study reports the isolation of A.salmonicida salmonicida from C.auratus in North China and provides a reference strain and a research foundation for further studies on A.salmonicida disease control and epidemiology. | Shibo Jin Songzhe Fu Ruijun Li Huifeng Dang Dongxu Gao Shigen Ye Zhiqiang Jiang | 2020 | Aquaculture and Fisheries2020，5，1： | 1 |
| 5 | A fuzzy-rule-based Couzin model显示文摘This paper proposes a modified Couzin and velocity-adaptive Couzin flocking model based on fuzzy rules. In the models, agents update their positions through a fuzzy-rule-based decision-making scheme in three perception zones. Stability of the systems are guaranteed. Simulations demonstrate that the convergence probability and relative converging size are both improved. | Hairong DONG Yan ZHAO Shigen GAO | 2013 | 控制理论与应用(英文版)2013，11，2： | 0 |
