The invention discloses a heavy-load train speed tracking control method for long and large downhill cyclic braking, and the method comprises the steps: designing a heavy-load train speed tracking controller based on a disturbance observer and a self-adaptive iterative learning method, and carrying out the parameter self-adaption of the controller through the effective utilization of the information in the train operation process; the application opportunity judgment of air braking does not depend on accurate modeling of a heavy haul train air braking system and does not depend on experience opportunity, and accurate tracking control over the train speed and position is achieved. According to the method, a control decision judgment standard is provided for circulating braking and relieving when the heavy-load train runs on the long and large downhill, and the running safety of the train is guaranteed.
