PMSM sliding-mode control based on novel reaching law and disturbance observer by LIU Jing, LI Hong-wen, DENG Yong-ting

“…To improve the performance of the speed servo system in the permanent magnet synchronous motor (PMSM) and to reduce the influence of disturbance in the control system, a sliding mode control method was proposed based on a novel reaching law and disturbance observer. A novel reaching law was presented to solve the contradiction between sliding mode surface reaching time and the system chattering in the regular reaching law, and which can simultaneously improve the system response speed. …”

The medial fronto-parietal network of the macaque: Different specializations for spatial parameters of reaching? by Marina De Vitis, Matteo Filippini, Kostas Hadjidimitrakis, Francesco Edoardo Vaccari, Stefano Diomedi, Michela Gamberini, Martina Gori, Michele Testa, Claudio Galletti, Patrizia Fattori

“…Extensive research in premotor areas primarily focused on center-out reaches, which did not account for reach depth. Therefore, it is unknown whether tuning by spatial and motor variables, such as reach direction and depth, is similar in frontal and parietal cortices and whether there are differences in the temporal evolution of activity that reflects functional specializations. …”

An adaptive sliding mode fault-tolerant control of variable speed reaching law for steer-by-wire systems by Jinwen Yang, Yinquan Yu, Dequan Zeng, Yiming Hu, Junhui Liu, Kai Liu, Giuseppe Carbone, Shaohua Luo, Xiaofeng Zhu

“…To solve the inadequate tracking accuracy resulting from actuator fault and system disturbances, an adaptive sliding mode fault-tolerant control strategy based on a variable-speed reaching law (VSRL-ASMFTC) is proposed. By integrating an adjustment function into the constant-velocity reaching polynomial and designing an adaptive law, dynamic updating of the control law is achieved. …”

Research on Relationship Between Runoff of Upper Reaches of the Yellow River and Sea Surface Temperature and Atmospheric Circulation Characteristics by WANG Dan, PAN Hongzhong, BAI Yu

“…Precipitation in any watershed is a part of the global atmosphere and water cycle.Most of the water in the atmosphere comes from seawater evaporation.The amount of water vapor is directly related to the sea surface temperature (SST),which is the main driving factor of water cycle.It is a very complicated process that seawater evaporates into the atmosphere,and the water in the atmosphere falls on a certain watershed and forms runoff.In order to increase the forecast period of runoff,the teleconnection relationship between SST and runoff has attracted more and more attention.By using the natural orthogonal function decomposition method and correlation analysis,this paper establishes the correlation between the runoff in the upper reaches of the Yellow River and the corresponding sea surface temperature,and then verifies and analyzes the formation mechanism from the perspective of atmospheric circulation.The results show that the change of sea surface temperature is closely related to the runoff of upper reaches of Yellow River in flood season.…”
