中文摘要：
提出了运用模式控制的方法提高车辆的曲线通过性憾．并将其运用于一个简化的二轴车，先建立车辆系统总体动力学模型，而后将其车体横移和摇头运动解耦，再分别对两模式分别设计控制器.为了保证系统具有一定的鲁棒性，设计过程中亦将蠕滑系数、接触点踏面斜度的适时变化考虑进去。最终借助于Matlab的Simulink进行建模，仿真结果表明，相对于传统被动悬挂式车辆该自动控制车辆具有更强的曲线通过能力。
英文摘要：
A modal control strategy to improve the curving performances of railway vehicle was proposed and applied to a two-axle vehicle. First ,the vehicle dynamics model was set up, and then it＇s lateral and yaw motions were de-coupled to allow the individual design of their active controller. To ensure the robustness of the system, the variations of the creep coefficient and wheelset conicity were considered in the design. The Simulink block of MATLAB was uesd as environment for the realization of the system at last. Simulation result shows that the vehicle equiped with actively steered wheelset performs much better than a passive vehicle on a curved track.
