Abstract:

Real-time fault diagnosis of urban rail train braking system is an important means for the stable and safe operation of urban rail transit. Based on the real time data acquisition of urban rail train braking system, a braking system control model is established with linear matrix inequality (LMI) theory, and then a residual generator is designed for system control output. It calibrates the key parameters of the residual generator and threshold of the fault residual generator, based on the application of control theory. A real-time fault diagnosis method is put forward for urban rail train. Simulation results show that the fault diagnosis method is real-time and availability.

Key words: intelligent transportation, urban rail train, brake system, fault diagnosis, LMI, decentralized system, residuals estimates

摘要:

城轨列车制动系统在途故障诊断方法是增强列车运行安全性的一个重要手段.本文基于城轨列车制动过程实时检测数据,采用线性矩阵不等式(LMI)和分散式控制的理论方法,建立了列车制动系统控制模型、列车及车厢的制动状态残差发生器,提出了残差发生器关键参数及故障阈值的标定方法,形成了城轨列车制动系统在途故障诊断方法.通过仿真实验,验证了诊断方法的有效性与实时性.
