Online Estimation of the Adhesion Coefficient and Its Derivative Based on the Cascading SMC Observer
The adhesion coefficient of wheel-rail surface cannot be directly measured, so a cascaded sliding-mode observer is proposed to observe adhesion coefficient and its derivative. A kinetic model for running heavy-duty locomotive is also established. The state equation of wheel adhesion control system i...
