Detailed longitudinal train action model

WebA three-degree-of-freedom model adds longitudinal acceleration to the model, therefore enabling one to describe the full vehicle motion in the X-Y plane. As shown in Figure 2.6, the longitudinal velocity, U, and the longitudinal force, Ftf and Ftr, are included into the model. This is the model that is used throughout this research. WebApr 6, 2024 · For stability control, the active safety control layer already has a detailed dynamic model; the required additional yaw moment and longitudinal force can be well solved using model-based control methods such as optimal control or sliding mode control. Therefore, it is not appropriate to use direct RL control in the active safety control layer.
