The invention discloses a virtual coupling high-speed train group cooperative operation control method, which specifically comprises the following steps of: aiming at a plurality of high-speed trains on the same line, respectively establishing a longitudinal dynamic model of each train; establishing a multi-train communication topological structure based on an adjacent communication mode; according to the current running state of the train, the latest running state of the previous train and the braking characteristic parameters of all the trains, the minimum safety tracking interval needing to be kept during cooperative running of the virtual coupling trains is calculated in real time; converting the train dynamical model with the running state constraint into a new train dynamical model without state constraint by adopting a nonlinear state dependence function; based on a backstepping method, a dynamic surface technology, an auxiliary dynamic system method and an adaptive method, a multi-train anti-saturation distributed cooperative controller is designed. According to the method, the train tracking interval can be further compressed, cooperative operation control over the high-speed train group with different initial states is achieved, and the railway transport capacity is greatly improved while the train operation safety is guaranteed.
