The invention relates to the technical field of wireless communication. The invention discloses a train wireless network time delay compensation control method, which comprises the following steps of: acquiring time delay data from a central control unit to a traction control unit to form a time delay sequence; processing the time delay sequence to obtain a residual error and a component value; constructing a time delay prediction model, and inputting the obtained residual and component values into the time delay prediction model to obtain a time delay prediction value at the next moment; the obtained time delay prediction value at the next moment is input into a train operation controller, and operation control over the train is achieved through the train operation controller; and constructing an evaluation index for evaluating the control performance of the train operation controller. According to the method, the collected time delay sequence with high complexity is decomposed into the sub-sequences with low complexity, the data complexity is reduced, the parameters of the LSSVM prediction model are optimized through the chaos particle swarm algorithm, the prediction accuracy is improved, the parameters required by the controller can be automatically optimized, and it is guaranteed that the control effect is optimal.
