Research on Feed Forward Adaptive-generalized Model Predictive Control for High-speed Train Automatic Operation

Autor: LUO Yuan, YI Jie, BAI Jinlei, ZHANG Zhengfang

Publikováno v: Kongzhi Yu Xinxi Jishu, Iss 1, Pp 14-22 (2024)

High-speed automatic train operation (ATO) systems inherently exhibit strong nonlinearity and uncertainty. In view of the characteristics of nonlinearity and time-variability of high-speed train model parameters, this paper proposes a feed forward ad

Prediction Method of Air Braking Force of Heavy Load Train Based on Fuzzy Logic-based Neural Network

Autor: SHI Ke, ZHANG Zhengfang, BAI Jinglei, JIANG Jie

Publikováno v: Kongzhi Yu Xinxi Jishu, Iss 1, Pp 1-6 (2022)

Due to the strong nonlinearity of air braking of heavy load train, the large error of feedback decompression amount, and the coupling relationship between charging and exhaust time and decompression process, it is difficult to guarantee the operation

Report

The Calculus of Boundary Variations and the Dielectric Boundary Force in the Poisson-Boltzmann Theory for Molecular Solvation

Autor: Li, Bo, Zhang, Zhengfang, Zhou, Shenggao

In a continuum model of the solvation of charged molecules in an aqueous solvent, the classical Poisson-Boltzmann (PB) theory is generalized to include the solute point charges and the dielectric boundary that separates the high-dielectric solvent fr
