The invention relates to a train operation control method under random interference, which comprises the following steps of: constructing a train time-varying multi-mass-point dynamic model under the condition of considering that a train is subjected to random interference; a position relative offset error is calculated based on a given ideal position relative offset and an actual relative position offset, a speed tracking error is calculated based on a given target speed curve and a carriage speed, and an error state equation is established based on the position relative offset error and the speed tracking error. Designing a time-varying state feedback controller capable of meeting a constraint condition based on the error state equation, and converting the constraint condition into a time-varying differential matrix inequality; according to the method, the time-varying state feedback controller meeting the time-varying differential matrix inequality condition is solved, and the operation of the train is controlled based on the solved time-varying state feedback controller, so that the train can effectively meet the stability requirement under the condition that the train is subjected to random interference and also has good transient performance, and the cost is ensured to reach the minimum.
