Train speed tracking control method, operation control device and computer storage medium

Abstract

The invention discloses a train speed tracking control method, an operation control device and a computer storage medium. The method comprises the following steps: acquiring an actual speed and an expected speed of a train; according to the actual speed and the expected speed, obtaining the acting force needing to be adjusted of the train through fuzzy logic control; and according to the acting force, updating the actual speed through a unit-shift multi-mass-point model. According to the method, the actual speed can be continuously obtained and compared with the expected speed, a nonlinear feedback closed-loop control mode is adopted, modeling errors can be suppressed, interference and noise can be suppressed, and the method has the advantages of being high in robustness, high in responsespeed, small in tracking error and the like. Secondly, the acting force needing to be adjusted by the train can be rapidly obtained through fuzzy logic control, and a corresponding traction force or braking force can be applied to the train. Finally, the actual speed of the train is changed by adopting a unit-shift multi-mass-point model, the acting force between compartments is also considered, the dynamic behavior of the train can be better described, and the calculation is not complex.

Problems solved by technology

[0003] For the train dynamic model, it can often be established by applying the dynamic principle of Newton's second law. However, due to the complexity of the train operating environment and the nonlinearity of the operating process, it is difficult to obtain an accurate train dynamic model.

However, the existing train dynamic models often include single-mass model and multi-mass model. The shortcoming of the single-mass model is that it does not consider the interaction force between train cars, while the multi-mass model is more accurate and closer to that of the single-mass model. The actual situation, but the disadvantage of the multi-particle model is that its calculation is more complicated
