Train System Identification Based on the Analysis of Real-Time Running Data

Abstract— The train operation system is a time-varying nonlinear process. Most of the traditional train system identifications cannot describe the uncertain changes in actual operation. In this paper, we propose a time-varying nonlinear train model by analyzing the train operation process. AM-VFF-RLS method is applied to identify the parameters online. The simulation results verify that the model and identification method used in this paper can identify the characteristics of train operation system online and accurately.

Index Terms— ATO; system identification; auxiliary model; recursive least square method; forgetting factor.
