高速列车横向稳定控制系统模型机理研究

从最佳控制角度，研究了摆式列车的横向稳定控制机理：在最小阻力的摄动方向上，通过横向悬挂施加有效的液压控制作用；在过渡曲线通过时，车体残余未平衡惯性作用，通过离心加速度的反馈加以“抵制”．为此，多刚体系统在这一方向上建立等效模型，并与液压系统以耦合方式进行系统集成．由于非线性线系统行为呈现明显的稳态特征，据此可以建立反映系统行为规律的参考模型．利用Simulink/NCD模块，设计验证控制器参数及其鲁棒性．

Study of Modei Mechanism od Control System for High-speed Tilt Train''''s Lateral Stability

From the viewpoint of optimal control, tilt train' s lateral stability control mechanism was studied: On the min. resistance DOF direction, the eflective hydraulic reference is govemed by Activity Lateral Suspension; When the coach running on the transitional curve, the residual nonbaknced inertial force is held off through the centrifugal acceleration feedback. Therefore, the multibody system converted into the mean effective modei on this direction which in turn is coupled with the Dydraulic system. Because the nonlinear integrated system's behaviors have the obvious steady characteristks, the reference modei can be estimated to represent the system behaviors' regularity. With SimuLink/NCD, the robust controller can be designed and validated.
