A data-driven integral sliding mode control method, system and device for a high-speed electric multiple unit (EMU) is provided, which relates to the field of operation control of EMUs. The method includes performing kinetic analysis on an operation process of a high-speed EMU to enable an input and output data set of the EMU to be equivalent to a multi-input-multi-output (MIMO) discrete-time nonlinear system; constructing an EMU full format dynamic linearization (FFDL) data model involving a generalized disturbance based on the MIMO discrete-time nonlinear system; designing an equivalent control law and a switching control law based on the FFDL data model; and establishing a MIMO EMU integral sliding mode control law, thus controlling the operation of the high-speed EMU. According to the present disclosure, the integral sliding mode control law is deduced based on the FFDL data model to conduct nonlinear control of the EMU.
