摘要

本文研究了电力牵引系统能量管理中的故障诊断问题。实际上，提出了DC-DC (Boost和Buck/Boost)功率变换器的双线性模型。回顾了利用未知输入的观测器进行残差产生的分析方法，利用残差产生器的计算方法对存在干扰的系统进行故障检测和隔离。为了说明该方法的有效性，利用Matlab/simulink进行了仿真。

Faults detection and isolation for energy management system in electric traction

This paper deals with the problem of diagnosis of faults in energy management for electric traction system. In fact, a bilinear model for the DC-DC (Boost and Buck/Boost) power converters is proposed. The analytical approach of residual generation using the observers with unknown inputs is reviewed, the computation of a bank of residual generators is exploited for fault detection and isolation, in the presence of disturbance. To illustrate the effectiveness of this method, simulations using Matlab/simulink are carried out.
