The invention discloses a train speed tracking control method based on an equivalent sliding mode and an RBF (Radial Basis Function) neural network, belongs to the technical field of train speed tracking, and provides a neural network equivalent sliding mode controller for a control target based on strong nonlinear interference in a train running process so as to enhance the robustness of a control system. Sliding mode control is introduced, and the effectiveness of the algorithm is verified through simulation; in order to suppress an inherent buffeting phenomenon of sliding mode control in a convergence process, a rule base is established by combining excellent driver driving experience on the basis of a sliding mode control algorithm framework, a neural network trainer is established, and a switching gain obtained through training effectively softens a discontinuous switching phenomenon so as to weaken buffeting, so that the stability of the sliding mode control algorithm is improved. According to the invention, the anti-disturbance capability and the control precision of the system are enhanced, it can be ensured that the train accurately tracks the reference trajectory during operation, control input is smoothed, the chattering phenomenon is weakened, and frequent switching and overshoot of working condition switching points are avoided.
