The invention discloses a magnetic track brake application control system and method. The control system comprises a brake microcomputer unit, a brake power supply, a magnetic track brake control unit, a brake pipe and a magnetic track brake; the magnetic track brake comprises an air cylinder and a pole shoe; a piston rod of the air cylinder is fixedly connected with the pole shoe; and the controlsystem further comprises a normally-closed analog electric pneumatic valve. The magnetic track brake control unit is provided with a first current linear amplification unit and a second current linear amplification unit; the brake power supply is electrically connected with the control end of the analog electric pneumatic valve through the first current linear amplification unit; the brake pipe is connected with the air inlet end of the air cylinder through the analog electric pneumatic valve; and the brake power supply is electrically connected with a magnet exciting coil in the pole shoe through the second current linear amplification unit. When magnetic rail braking is applied, the air pressure of the air supply pipeline of the air cylinder is controlled to be linearly increased so asto control the falling speed of the pole shoe, meanwhile, linear current is output to the magnet exciting coil, it is guaranteed that a vehicle cannot generate large impact when magnetic rail brakingis switched on, and the riding comfort of passengers is improved.
