The invention discloses a train operation control optimization method based on time-varying parameter identification, and the method comprises the following steps: S1, determining input and output data through the recording of vehicle-mounted equipment in the train operation process, analyzing the time-varying parameters, needing to be identified, of a train, and building a basic train model; s2, through auxiliary model processing aiming at actually acquired data, a train operation model based on an auxiliary model is obtained; and S3, applying the train operation model obtained in the step S2 to a train control system, and performing optimization control on train operation. The method is based on data-driven parameter identification, starts from actual input and output data, considers the variation of the actual train operation environment, can well track the environment change by continuously iteratively updating information and accelerating the attenuation of historical data by a forgetting factor, has lower prediction error, and can be used for realizing the time-varying parameter identification. And optimization of train control can be realized.
