Abstract
A method for stopping a train at a range of predetermined positions, first acquires a measured state of the trains, and then updates, in a parameter estimator, estimates of unknown parameters and a reliability of the unknown parameters, based on a comparison of a predicted state of the train with the measured state of the train. An excitation input sequence reference generator acquires dynamics of the train to determine a sequence of excitation inputs based on a current estimate of system parameters, the measured state of the train, and a set of constraints on an operation of the train. A model predictive controller (MPC) receives a control-oriented cost function, a set of constraints, the sequence of excitation inputs, the estimate of the unknown parameters and the reliability of the estimate of the unknown parameters to determine an input command for a traction-brake actuator of the train.
