Patent number: 12003203Abstract: A model predictive decomposition control method and device for an open-winding five-phase permanent magnet synchronous motor is provided. The method includes obtaining the voltage component in the stationary coordinate system under the orientation of the rotor magnetic field, synthesizing the virtual voltage vector that can eliminate the voltage vector in harmonic space according to the vector distribution of the five-phase permanent magnet synchronous motor under the voltage source inverter. The open winding permanent magnet synchronous motor topology is equivalent to the superposition of the independent actions of two inverters. The voltage vector generated by a single inverter is predicted through the mathematical model of the motor. The expected increment is a judgment condition to determine whether the open winding system uses one of the two inverters to maintain the normal operation of the open winding system, or the first inverter is clamped and the second inverter generates the remaining increment.Type: GrantFiled: December 4, 2020Date of Patent: June 4, 2024Assignee: JIANGSU UNIVERSITYInventors: Jinghua Ji, Yuxuan Du, Wenxiang Zhao, Linsen Huang, Tao Tao

Publication number: 20240173395Abstract: Provided in the present disclosure are a Zika/dengue vaccine and its application thereof. The present disclosure introduces a mutation into the E-protein FL fusion region of the Zika virus or dengue virus. Antigens with said mutations are unable to bind to antibodies that causes ADE. After immunization with the vaccine of the present disclosure acquired from the said antigens, production of FL epitope-induced antibodies can be prevented, thereby reducing or eliminating the ADE effect.Type: ApplicationFiled: November 9, 2020Publication date: May 30, 2024Applicant: Institute of Microbiology, Chinese Academy of SciencesInventors: Fu GAO, Lianpan DAI, Jinghua YAN, Kun XU, Yuxuan HAN, Qihui WANG, Qingrui HUANG, Jinhe LI
