The invention discloses a high-speed train group distributed data driving control method under fault saturation, and the method specifically comprises the steps: building a high-speed train group dynamic model through the Newton's law, and carrying out the discretization and normalization; carrying out equivalent linearization on the nonlinear model by utilizing a pseudo partial derivative and a differential median theorem; establishing a criterion function about system data model parameters and control signals, and preliminarily obtaining a distributed data driving control scheme of the train group according to optimization conditions; establishing an intermittent actuator fault and nonlinear input saturation model existing in the running process of the high-speed train, and introducing a multi-agent theory and a parameter resetting algorithm to obtain a data-driven high-speed train group distributed anti-saturation robust control method; and performing test verification on a numerical simulation platform, and transplanting to a high-speed train automatic operation system. The method gets rid of dependence on a train model, is simple in structure and easy to implement, and can improve the utilization rate of inter-station lines and the transportation efficiency of a high-speed train.
