Wheel Slip Prevention Control Based on Nonlinear Robust Control Theory

This paper presents a robust wheel slip prevention control system for railway vehicles that uses sliding mode control. It is essential to consider the robustness, since there are model uncertainties that result from nonlinear characteristics for adhesion and the brake material friction coefficient. Simulations are performed and compared with conventional control laws. Results indicate that the proposed wheel slip control system based on sliding mode control is very stable and robust against changes such as in adhesion forces, brake material friction coefficients and vehicle weight. The new system also shows high brake performance under non-linearity of brake dynamics.
