| 2 | Adaptive Trajectory Tracking Control for a Nonholonomic Mobile Robot显示文摘As one of the core issues of the mobile robot motion control, trajectory tracking has received extensive attention. At present, the solution of the problem only takes kinematic or dynamic model into account separately, so that the presented strategy is difficult to realize satisfactory tracking quality in practical application. Considering the unknown parameters of two models, this paper presents an adaptive controller for solving the trajectory tracking problem of a mobile robot. Firstly, an adaptive kinematic controller utilized to generate the command of velocity is designed based on Backstepping method. Then, in order to make the real velocity of mobile robot reach the desired velocity asymptotically, a dynamic adaptive controller is proposed adopting reference model and Lyapunov stability theory. Finally, through simulating typical trajectories including circular trajectory, fold line and parabola trajectory in normal and perturbed cases, the results illustrate that the control scheme can solve the tracking problem effectively. The proposed control law, which can tune the kinematic and dynamic model parameters online and overcome external disturbances, provides a novel method for improving trajectory tracking performance of the mobile robot. | CAO Zhengcai ZHAO Yingtao WU Qidi | 2011 | Chinese Journal of Mechanical Engineering2011，24，4： | 13 |
| 3 | 基于有限元法的硬脑膜外视皮层电刺激仿真研究显示文摘经硬脑膜对视皮层电刺激是治疗失明的新思路。为从理论上认识其作用机制,首先建立视皮层区域的有限元仿真模型,分析脑组织内电场分布,并用激活函数和组织活化区来表征外加刺激的作用效果;随后逐次改变单相脉冲的幅值、脉宽和频率,通过基波作用下组织活化区的变化来探讨不同刺激参数对结果的影响。仿真结果显示,经硬脑膜可以实现对视皮层的有效刺激,只是所需刺激强度比直接皮层刺激约高30倍;多电极刺激模式下,只要电极间距超过5 mm,电极间的影响可忽略不计;降低幅值、脉宽和频率等参数,可以改善单相方波脉冲的刺激效果,其中幅值的减小对空间分辨率的提高效果最为显著。所得结论对实验具有一定指导意义。 | 侯文生 章毅 郑小林 吴小鹰 阴正勤 JIANG Yingtao BISWAJIT Das | 2010 | 中国生物医学工程学报2010，29，4： | 9 |
| 4 | An overview of resistive random access memory devices显示文摘With recent progress in material science, resistive random access memory (RRAM) devices have attracted interest for nonvolatile, low-power, nondestructive readout, and high-density memories. Relevant performance parameters of RRAM devices include operating voltage, operation speed, resistance ratio, endurance, retention time, device yield, and multilevel storage. Numerous resistive-switching mechanisms, such as conductive filament, space-charge-limited conduction, trap charging and discharging, Schottky Emission, and Pool-Frenkel emission, have been proposed to explain the resistive switching of RRAM devices. In addition to a discussion of these mechanisms, the effects of electrode materials, doped oxide materials, and different configuration devices on the resistive-switching characteristics in nonvolatile memory applications, are reviewed. Finally, suggestions for future research, as well as the challenges awaiting RRAM devices, are given. | LI YingTao LONG ShiBing LIU Qi LU HangBing LIU Su LIU Ming | 2011 | Chinese Science Bulletin2011，56，28： | 9 |
| 5 | An elastic-plastic contact model for line contact structures显示文摘Although numerical simulation tools are now very powerful,the development of analytical models is very important for the prediction of the mechanical behaviour of line contact structures for deeply understanding contact problems and engineering applications.For the line contact structures widely used in the engineering field,few analytical models are available for predicting the mechanical behaviour when the structures deform plastically,as the classic Hertz’s theory would be invalid.Thus,the present study proposed an elastic-plastic model for line contact structures based on the understanding of the yield mechanism.A mathematical expression describing the global relationship between load history and contact width evolution of line contact structures was obtained.The proposed model was verified through an actual line contact test and a corresponding numerical simulation.The results confirmed that this model can be used to accurately predict the elastic-plastic mechanical behaviour of a line contact structure. | Haibin Zhu Yingtao Zhao Zhifeng He Ruinan Zhang Shaopeng Ma | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，5： | 8 |

Based on a Cu/ZrO2/Pt device, three doping technologies with Ti ions, Cu, and Cu nanocrystal, respectively, are adopted in the experiments. Compared to an undoped device, improvements focus on four points: eliminating the electroforming process, reducing operation voltage, improving electrical uniformity, and increasing device yield. In addition, thermal stability of the high resistance state and better retention are also achieved by the doping technology. We demonstrate that doping technology is an effective way of improving the electrical performance of RRAM. | WANG Yan LIU Oi LU HangBing LONG ShiBing WANG Wei LI YingTao ZHANG Sen LIAN WenTai YANG JianHong LIU Ming | 2012 | Chinese Science Bulletin2012，57，11： | 6 |
| 9 | Nanoparticle monolayer-based flexible strain gauge with ultrafast dynamic response for acoustic vibration detection显示文摘The relatively poor dynamic response of current flexible strain gauges has prevented their wide adoption in portable electronics. In this work, we present a greatly improved flexible strain gauge, where one strip of Au nanoparticle (NP) monolayer assembled on a polyethylene terephthalate film is utilized as the active unit. The proposed flexible gauge is capable of responding to applied stimuli without detectable hysteresis via electron tunneling between adjacent nanoparticles within the Au NP monolayer. Based on experimental quantification of the time and frequency domain dependence of the electrical resistance of the proposed strain gauge, acoustic vibrations in the frequency range of 1 to 20,000 Hz could be reliably detected. In addition to being used to measure musical tone, audible speech, and creature vocalization, as demonstrated in this study, the ultrafast dynamic response of this flexible strain gauge can be used in a wide range of applications, including miniaturized vibratory sensors, safe entrance guard management systems, and ultrasensitive pressure sensors. | Lizhi Yi Weihong Jiao Ke Wu Lihua Qian Xunxing Yu Qi Xia Kuanmin Mao Songliu Yuan Shuai Wang Yingtao Jiang | 2015 | Nano Research2015，8，9： | 6 |

| 12 | Flexible control strategy for HVDC transmission system adapted to intermittent new energy delivery显示文摘Intermittent new energy delivery requires increasing the flexibility of ultra-high voltage direct current(DC)power adjustment.Based on a converter steady-state model and a DC power model,the control angle constraints of a converter valve are relaxed for power regulation.In this paper,a flexible DC power control method based on a fixed tap changer position is proposed.The initial ratio of the converter transformer is optimized.The effects of the fixed-tap changer position control on the control angle,reactive power compensation,and commutation failure are analyzed.The new control method allows a DC system to operate at a large angle and increase the additional reactive power loss while improving the commutation security margin.Steady-state and electromagnetic transient simulations in the CIGRE test system verify the validity of the method proposed in this paper and the correctness of the analysis conclusions. | Chenhao Li Kuan Li Changhui Ma Pengfei Zhang Qi Tao Yingtao Sun Xin Wang | 2021 | Global Energy Interconnection2021，4，4： | 6 |
| 13 | Thermal reliability analysis and optimization of polymer insulating through-silicon-vias(TSVs) for 3D integration显示文摘Polymer insulating through-silicon-vias(TSVs)is an attractive approach for high-performance 3D integration systems.To further demonstrate the polymer insulating TSVs,this paper investigates the thermal stability by measuring the leakage current under bias-temperature condition,studies the thermal stress characteristics with Finite Element Analysis(FEA),and tries to improve the thermal mechanical reliability of high-density TSVs array by optimizing the geometry parameters of pitch,liner and redistribution layer(RDL).The electrical measurements show the polymer insulating TSVs can maintain good insulation capability(less than 2 10 11A)under challenging bias-temperature conditions of 20 V and 200 C,despite the leakage degradation observation.The FEA results show that the thermal stress is significantly reduced at the sidewall,but highly concentrates at the surface,which is the potential location of mechanical failure.And,the analysis results indicate that the polymer insulating TSVs(diameter of 10 m,depth of 50 m)array with a pitch of 20 m,liner thickness of 1 m and RDL radius of 9m has an optimized thermal-mechanical reliability for application. | ZHONG ShunAn WANG ShiWei CHEN QianWen DING YingTao | 2014 | Science China(Technological Sciences)2014，57，1： | 5 |

| 17 | 经颅磁刺激对握力影响机理的初步研究显示文摘目的:探讨在不同刺激强度和不同手部握力输出的条件下,磁刺激前后对握力大小的改变。方法:10名健康受试者,其右手分别以3个不同的背景力量握住握力计,用圆形磁刺激线圈刺激左侧运动皮层,施加的刺激强度从阈值开始,每次递增10%,记录磁刺激施加前后握力输出的变化。结果:对于同一背景握力,刺激强度越大,握力大小的峰峰值及负峰值也越大;而在刺激强度不变的情况下,握力波形的峰峰值和负峰值也随握力的增大而增大;输出握力波形的正峰值和恢复时间与刺激强度、背景握力大小无明显关系。结论:实验结果提示握力峰峰值及负峰值的变化可能与参与肌肉收缩的运动单位数量及其兴奋性有关。 | 何艳 侯文生 郑小林 吴小鹰 Jiang Yingtao Zheng Jun 彭承琳 | 2008 | 中国生物医学工程学报2008，27，6： | 3 |
| 18 | A Novel Approach for QoS Prediction Based on Bayesian Combinational Model显示文摘As an important factor in evaluating service,QoS(Quality of Service) has drawn more and more concerns with the rapid increasing of Web services. However,due to the great volatility of services in Mobile Internet environments,such as internet of vehicles,Web services often do not work as announced and thus cause unacceptable problems. QoS prediction can avoid failure before it takes place,which is considered a more effective way to assure quality. However,Current QoS prediction approaches neither consider the highly dynamic of Web services,nor maintain good prediction performance all the time. Consequently we propose a novel Bayesian combinational model to predict QoS by continuously adjusting credit values of the basic models so as to keep good prediction accuracy. QoS attributes such as response time,throughput and reliability are used to validate the proposed model. Experimental results show that the model can provide stable prediction results in Mobile Internet environments. | Pengcheng Zhang Yingtao Sun Hareton Leung Meijun Xu Wenrui Li | 2016 | China Communications2016，13，11： | 3 |

| 20 | 经硬脑膜电刺激对视皮层神经活动影响的仿真研究显示文摘经硬脑膜对视皮层电刺激为视觉功能修复提供了一种新的技术思路。前期的仿真工作利用激活函数定性研究了经硬脑膜电刺激对视皮层的作用效果,本研究在原有模型基础上引入神经元模型,定量研究不同刺激波形及参数对电极作用范围的影响。该方法将已建立的神经元模型耦合到视皮层区域有限元模型中,利用傅里叶-有限元方法分别计算双脉冲、指数脉冲和正弦波刺激下视皮层区域模型内的场电位,将电位加载到神经元模型上,观察神经元是否发生兴奋,以神经元区域兴奋个数判定电极的作用范围。仿真结果表明,该方法能较好的表达刺激的响应范围:不同刺激波形及参数引起的神经元区域兴奋数量不同,且解剖结构会影响刺激效果。所得结果对实验具有一定指导意义。 | 夏楠 侯文生 章毅 郑小林 吴小鹰 阴正勤 JIANG Yingtao | 2011 | 中国生物医学工程学报2011，30，5： | 2 |
