The invention discloses a guide constraint control method for a maglev high-speed rail under network attacks, and belongs to the field of rail transit. The method adopts a dynamic air gap constraint and boundary layer sectional type continuous adjustment technology to perform anti-network attack control on the maglev high-speed rail guide system: establishing a dynamic mathematical model and a lateral centrifugal force model of the maglev high-speed rail guide system, and further obtaining a state-space equation and a centrifugal force suppression control rate of the maglev high-speed rail guide system; constructing a satellite navigation network attack model of the maglev high-speed rail track and driving information; converting a state-space equation of the magnetic levitation high-speed rail guiding system into a control equation of the magnetic levitation high-speed rail guiding system containing wind shear disturbance and guiding force mismatch matching interference; dynamic constraint control is adopted, a guiding controller is designed, and guiding constraint control over the magnetic levitation high-speed rail under network attacks is achieved. While the starting stability of the maglev high-speed rail is improved, mismatch of the guiding force is rapidly compensated, and stable operation of the maglev high-speed rail is guaranteed.
