摘　　要：针对高速列车动态系统研究了鲁棒故障诊断滤波器的设计问题。首先,通过引入多质点力学模型刻画了高速列车动态特性,并将线性化过程中产生的高阶项以及由轨道曲线阻力、坡度以及隧道阻力造成的非线性不确定阻力建模为具有特定方向性特征的外界干扰。其次,将高速列车常发的牵引系统故障、传感器组故障以及车体结构故障归结为两类故障模型,通过建立两类故障的等价关系,在故障诊断滤波器设计过程中将本文考虑的三种故障统一化为类执行器故障进行处理。最后,针对高速列车动态系统多质点模型,基于几何方法通过系统左特征向量配置设计鲁棒故障诊断滤波器,并进行了数值仿真,仿真结果验证了本故障诊断滤波器设计方法的有效性。The fault diagnosis filter design problem of high speed train was systematically studied in this paper. First, a multi-particle model was introduced to describe the dynamics of the high speed train. The high order nonlinear terms generated in the linearization procedure and the complex nonlinear uncertainty terms generated by curve resistance, slop resistance and tunnel resistance were modeled as a series of directional exogenous disturbance. Then, the faults frequently occurring to the high speed train including hauling system fault, sensor set fault and body structure fault were categorized into two types of models. By constructing the equivalent relations of the two types of faults, the three kinds of faults were treated as a unified class executor fault in the design of fault diagnosis filter. Finally, Based on the dynamic multi-particle model of the high speed train, a robust fault diagnosis filter was designed through the left eigenvector assignment on the basis of geometric method. A numerical simulation was con- ducted and the results verified the effectiveness of the proposed fault diagnosis filter.
