The invention relates to the technical field of rail transit, and provides a control method and device for a rail transit train braking system.The method comprises the steps that a state model of the braking system is established, a state variable is obtained by solving the state model, and the state model comprises external interference signals of the braking system; a sliding mode surface function of the braking system is established, and sliding mode surface information is obtained by solving the sliding mode surface function; calculating a parameter vector of the adaptive sliding mode controller; establishing a self-adaptive control law based on the external interference signal and the parameter vector of the self-adaptive sliding mode controller, and solving the self-adaptive control law to obtain a target control input signal of the braking system; and performing braking control on the rail transit train according to the sliding mode surface information and the target control input signal. Therefore, by considering the external interference and adjusting the train braking control strategy according to the external interference, the phenomena of energy waste, poor riding comfort, equipment abrasion and low operation efficiency can be reduced, the braking effect can be ensured, and the braking efficiency can be improved.
