| 1 | Regenerative Braking Strategy for Motor Hoist by Ultracapacitor显示文摘Rising concern in environmental issues on global scale has made energy saving in powered equipment a very important subject.In order to improve the energy efficiency and driving range of a motor hoist,a regenerative braking system is designed and discussed.The system takes a unique ultracapacitor-only approach to energy storage system.The bi-directional bride DC?DC converter which regulates current flow to and from the ultracapacitor operates in two modes:boost and buck,depending on the direction of the flow.In order to provide constant input and output current at the ultracapacitor,this system uses a double proportional-integral(PI) control strategy in regulating the duty cycle of PWM to the DC?DC converter.The permanent magnet synchronous motor(PWSM) drive system is also studied.The space vector pulse width modulation(SVPWM) technique,along with a two-closed-loop vector control model,is adopted after detailed analysis of PMSM characteristics.The overall model and control strategy for this regenerative braking system is ultimately built and simulated under the MATLAB and Simulink environment.A test platform is built to obtain experimental results.Analysis of the results reveals that more than half of the gravitational potential energy can be recovered by this system.Simulation and experimentation results testify the validity of the double PI control strategy for interface circuit of ultracapacitor and SVPWM strategy for PMSM. | BIAN Yongming ZHU Lijing LAN Hao LI Anhu XU Xinming | 2012 | Chinese Journal of Mechanical Engineering2012，25，2： | 7 |
| 2 | Even FIB Decomposition Model Based on Storage and Traffic Balancing显示文摘The sharp expansion of the FIB table rapidly aggravates the hardware cost of Line cards(LCs) in the high-performance distributed routers. The storage optimization of FIB becomes a research hotspot. The traffic load of each LC is still very different in the current nonfull backup storage, which has a deep impact on the overall forwarding performance of the routers. An even FIB decomposition model was proposed, namely FEST, aiming for a two-dimension balance in both storage and traffic. Based on the splitting and distribution filters, FEST starts with splitting the root prefixes and utilizes the optimal adaptation algorithm to evenly distribute the routing entries and the traffic to LCs without the modification of the hardware designs of the current LCs. Eventually FEST uses the location routing to determine the location and the forwarding of every packet. The experiment results show that different LCs get very even numbers of routing entries and relatively even traffic in FEST. | CHEN Wenlong WANG Shuxian TANG Xiaolan LAN Lijing | 2017 | Chinese Journal of Electronics2017，26，4： | 1 |
| 3 | Transcription factor OsSPL10 interacts with OsJAmyb to regulate blast resistance in rice显示文摘Transcription factors(TFs)play essential roles in transcriptional reprogramming during activation of plant immune responses to pathogens.OsSPL10(SQUAMOSA promoter binding protein-like10)is an important TF regulating trichome development and salt tolerance in rice.Here we report that knockout of OsSPL10 reduces whereas its overexpression enhances rice resistance to blast disease.OsSPL10 positively regulates chitin-induced immune responses including reactive oxygen species(ROS)burst and callose deposition.We show that OsSPL10 physically associates with OsJAmyb,an important TF involved in jasmonic acid(JA)signaling,and positively regulates its protein stability.We then prove that OsJAmyb positively regulates resistance to blast.Our results reveal a molecular module consisting of OsSPL10 and OsJAmyb that positively regulates blast resistance. | Zaofa Zhong Lijing Zhong Xiang Zhu Yimin Jiang Yihong Zheng Tao Lan Haitao Cui | 2024 | The Crop Journal2024，12，1： | 0 |
