Observer-based freight train control to reduce coupler strain and low adhesion issues

Abstract : This paper deals with the control design for freight trains, with the objective to reduce coupler failures and issues that might arise from low wheel-track adhesion. Since train cars are not equipped with position sensors, a cascade of observers is used to obtain finite-time estimations of in-train forces that cause coupler strain and adhesion level estimation. The controller is then aware of high amplitudes of in-train forces and of low adhesion situations, and adjusts the control signal accordingly, using LMI-based anti-windup technique. Simulation results show the benefits of the proposed approach.
