Design of Global Stable Anti-Skid Controller for High-Speed Train

Abstract
A global stable anti-skid control strategy for trains is proposed for the anti-skid and stability problems in high-speed train operation. Firstly, the asymmetric barrier lyapunov function is introduced into the design of the anti-skid controller to ensure the stability of the train in the feasible adhesion zone. Secondly, the sliding mode control is designed to constraint the slip speed variable, which is outside of the feasible adhesion zone, into the stable zone. By the switching of this hybrid controller, the global stable anti-skid control of the train is obtained. Both theoretical analysis and simulation experiment verify the stability and effectiveness of this control strategy. Keywords - Anti-skid, Asymmetric Barrier Lyapunov Function, Sliding Mode Control
