针对动车组列车制动系统的非线性及其在ATO中的重要性，从控制和动力学角度提出动车组列车制动系统的Hammerstein模型。根据制动指令信号的流向介绍动车组列车制动系统的工作过程；分别考虑系统各环节，用经过曲线拟合得到的静态非线性函数描述动车组列车制动特性表，用延时环节描述制动指令信号传输和制动控制器动作的延时，用两个一阶线性环节分别描述制动力反馈调节过程和动车组列车减速度冲动缓解过程，提出动车组列车制动系统的 Hammerstein模型；并介绍了思维进化算法辨识模型参数的方法。最后以CRH2型动车组为仿真对象验证模型和参数辨识方法的有效性。

The Hammerstein model of EMU braking system was ectablished in view of nonlinearity and impor-tance of the braking system in ATO(automatic train operation) .It was a kinetic model and accorded with the control law .The working process of the EMU braking system was introduced according to the transport mech-anism of braking instructions .The static nonlinear function obtained by curve fitting was used to depict the braking characteristics table and the delay system was used to describe the delay characteristics of the braking instruction transmission and the braking controller operation . One first-order linear system represented the feedback process of breaking .The other first-order linear system described the remission process of EMU accel-eration impulses .The above three links of braking constituted the Hammerstein model .Then ,the way how to identify model parameters with the mind evolutionary algorithm (MEA) was introduced .Finally ,simulation by EM U CRH2 proved the effectiveness of the proposed model and parameter identification algorithm .
