Observer-based brake control for railways

Research output: Conference contribution

Abstract

Since in a braking operation the shortest possible brake distance is required at all times an efficient and robust slip prevention control must be developed. The aim of this chapter is to present a control strategy based on an estimation method for the actual wheel-rail friction coefficient. A logic-based scheme that estimates a set point that prevents wheel slip is proposed. Having this estimation a conventional control algorithm maintains the system at the prescribed set point. If the external environment changes a new set point corresponding to the current condition is estimated. The estimation method is based on an adaptive observer design. The proposed control procedure does not rely on measured values of the slip ratio. The control algorithm is tested through simulation examples.
