Method for Evaluating Performance of Wheel Slide Protection Algorithm Using a Hybrid Simulator

Abstract

In performance evaluation of Wheel Slide Protection (WSP) systems, adjustment of the control algorithm by an on-track test is the most important process. However, since it is not easy to stably reproduce low adhesion conditions between wheels and rails in on-track tests, the control algorithm must be adjusted under different adhesion conditions for each run. Therefore, to solve this issue, we have developed a hybrid simulator that combines a real-time computer and pneumatic brake device. The developed simulator can specify arbitrary adhesion conditions, vehicle models, and control algorithms. This paper describes a method for evaluating the performance of the control algorithm for WSP using the hybrid simulator.
