摘　　要：应用H∞控制方法设计输出反馈控制器对机车车体垂向振动进行半主动控制,采用数值方法对设计结果进行仿真.结果表明,加入控制器后的悬挂系统对来自轨面的扰动对车体振动的影响有较强的抑制作用.An application of output feedback control with H_∞ method in vertical vibration of locomotive's body is proposed. In order to put semi active control on the body's vertical vibration, the H_∞ output feedback controller based on acting a manipulative force between the body and the bogie is designed. Numeric method is used to analyze the characteristic of the body's vertical vibration without controller or under controller,using MATLAB/SIMULINK to emulate the designing result. It's turned out that the body's vertical vibration which is aroused by the perturbation of rail is weakened with the application of the H_∞ controller.
