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.
