Train Velocity Tracking Control with Considering Wheel-Rail Adhesion
Velocity tracking plays a key role in train safe operation. Furthermore, the complex relation between wheels and rail affects velocity tracking. How to obtain a precise tracking algorithm with considering wheel-rail adhesion is a hard problem. This paper designs controllers in two cases respectively. The first algorithm is obtained based on the known wheel-rail adhesion model, while the second one is given with considering the unknown parameters of adhesion model. The simulation results comfirm the availability of the proposed controllers.
