| 1 | UPF based autonomous navigation scheme for deep space probe显示文摘The autonomous 'celestial navigation scheme' for deep space probe departing from the earth and the autonomous 'optical navigation scheme' for encountering object celestial body are presented. Then, aiming at the conditions that large initial estimation errors and non-Gaussian distribution of state or measurement errors may exist in orbit determination process of the two phases, UPF (unscented particle filter) is introduced into the navigation schemes. By tackling nonlinear and non-Gaussian problems, UPF overcomes the accuracy influence brought by the traditional EKF (extended Kalman filter), UKF (unscented Kalman filter), and PF (particle filter) schemes in approximate treatment to nonlinear and non-Gaussian state model and measurement model. The numerical simulations demonstrate the feasibility and higher accuracy of the UPF navigation scheme. | Li Peng Cui Hutao Cui Pingyuan | 2008 | Journal of Systems Engineering and Electronics2008，19，3： | 7 |
| 2 | Opportunities search of transfer between interplanetary halo orbits in ephemeris model显示文摘In this paper,a two-level search method for searching transfer opportunities between interplanetary halo orbits,exploiting the invariant manifolds of the restricted three-body problem,is proposed.In the method,the first-level search procedure is performed under the conditions of the initial time of escape manifold trajectory of the Sun-Earth halo orbit and the terminal time of capture manifold of the target planet fixed,by solving the optimal two-impulsive heliocentric trajectory to connect the two manifold trajectories.The contour map,helpful to the understanding of the global characteristics of the transfer opportunities,taking the initial time of escape manifold and the terminal time of capture manifold as variables,the optimal velocity increment of the first-level search as objective function,is used for the second-level search.Finally,taking the Earth-Mars and Earth-Venus halo to halo transfers for example,the transfer opportunities in 2015-2017 are searched.The results show the effectiveness of the proposed method and reveal the property of quasi-period of transfer opportunities between interplanetary halo orbits. | WANG YaMin CUI PingYuan QIAO Dong | 2013 | Science China(Technological Sciences)2013，56，1： | 4 |

| 5 | Geometry-based distributed arc-consistency method formultiagent planning and scheduling显示文摘This research focuses on building a distributed algorithm for planning and scheduling multiple agents to help people deal with events beyond their cognitive capacity, such as car assembly, factory management, spacecraft constellation, etc. We address not only the efficiency of the algorithm but also communication and the individual privacy. As to reason over the problems with multiple agents which are distributed but interconnected, a formal account of the Action-centric Multiagent Simple Temporal Problem(AMSTP) is put forward using the representation of geometries. The key technique we build on is a novel distributed arc-consistency algorithm centered by the geometric method called GDAC, which pays attention to how an agent's local subproblem affects other agents' subproblems. The GDAC is based on geometries taking the action rather than the timepoint as a variable, which can deal with continuous intervals and decrease the number of variables. Comprehensive experiments are run and the proposed technique outperforms the competitor and shows considerable merit compared to the centralized algorithm. | XU Rui LI ZhaoYu CUI PingYuan | 2019 | Science China(Technological Sciences)2019，62，1： | 2 |
| 6 | An improved nonlinear control strategy for deep space formation flying spacecraft显示文摘This paper aims to provide further study on thenonlinear modeling and controller design of formation flyingspacecraft in deep space missions. First, in the Sun-Earthsystem, the nonlinear formation dynamics for the circularrestricted three-body problem (CRTBP) and elliptic restrictedthree-body problem (ERTBP) are presented. Then, with theFloquet mode method, an impulsive controller is developedto keep the Chief on the desired Halo orbit. Finally, anonlinear adaptive control scheme based on Nonzero set-point LQR and neural network is proposed to achieve highprecision formation maneuver and keeping. The simulationresults indicate that the proposed nonlinear control strategyis reasonable as it considers not only the orbit keeping of theChief, but also the formation modeling inaccuracy. Moreover,the nonlinear adaptive control scheme is effective toimprove the control accuracy of the formation keeping. | Peng Li Pingyuan Cui Hutao Cui Deep Space Exploration Research Center,Harbin Institute of Technology, 150080 Harbin, China | 2009 | Acta Mechanica Sinica2009，25，6： | 2 |

| 17 | The preparation process and feature of the topological insulator Bi_2Te_3显示文摘Topological insulators are insulating in the bulk but have metallic surface states. Its unique physicochemical properties can find numerous applications in electronics, spintronics, photonics, the energy sciences, and the signal control of transportation. We report an experimental approach to synthesize the high-quality single crystal of topological insulator Bi2Te3by using self-flux method. We obtained the optimal preparation conditions by adjusting the parameters of heat treatment, and successfully prepared the single-crystal Bi2Te3sample. The as-grown samples have a surface with bright metallic luster and are soft and fragile. Furthermore, Bi2Te3has the obvious layer structure from SEM results. The data of X-ray diffraction and scanning electron microscope show that Bi2Te3single crystal grows along the c-axis with the order of Te(1)–Bi–Te(2)–Bi–Te(1)and crystallizes in the hexagonal system with space group of R/3 m. The q–T curve shows that q decreases with temperature, showing metallic behavior over the whole temperature range. | Peng Chen Dajin Zhou Pingyuan Li Yajing Cui Yongliang Chen | 2014 | Journal of Modern Transportation2014，22，1： | 1 |
