“…(2), determining the slip ratio depends on the longitudinal velocity. Since, in real conditions, the condition of the rail and wheel surface changes, and the longitudinal velocity of the train cannot merely be measured [45], [46]. In [42], a sensor-less approach is proposed to estimate the train longitudinal velocity.…”

“…For determining the e λ (k) and e v (k), λ k ð Þ and v k ð Þ must be estimated. Based on the slip ratio definition in Equation 2, determining the slip ratio depends on the longitudinal velocity, since in real conditions, the condition of the rail and wheel surface changes, and the longitudinal velocity of the train cannot merely be measured [44,45]. In Moaveni et al [41], a sensorless approach is proposed to estimate the train longitudinal velocity.…”

This study proposes an anti-slip control system for electric trains based on the fuzzy logic theory, which prevents the wheels from slipping during the acceleration and simultaneously tracks the desired speed profile. To improve the control performance, the train longitudinal velocity and the slip ratio are estimated. By using a Field Oriented Control (FOC), the angular speed of the traction motor is controlled. The fuzzy control system determines the desired angular speed of the traction motor as the reference input of FOC to obtain the desired slip ratio and track the desired speed profile. Simulation results show the effectiveness of the control system in various wheel-rail surface conditions based on the real parameters of ER24PC locomotive.
