“…Lu et al [27] presented a robust adaptive cooperative control to control the slip velocity in high-speed trains. He et al and Zhao et al [28,29] introduced an integral sliding mode control to obtain the optimal adhesion. The advantage of the method is its robustness in dealing with model uncertainty and disturbances, while the dynamics of the traction motors has not been considered in the model.…”

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.

“…Also, while driving the locomotive, slipping may occur when, for example, at a given moment, we increase the tractive force above the adhesion curve, causing the slipping of the driving wheels [5]. However, such cases occur because modern locomotives are designed in such a way that the drivers mounted on them enable the control of the drive so that the maximum power of the vehicle is used to the full by appropriate control of the coefficient of adhesion and slip speed [3,5,7].…”

One of the most critical elements ensuring the proper operation of locomotives are devices that detect and eliminate slipping, especially during the start-up of the locomotive in difficult operating conditions. Various types of slip control systems and methods are used on traction vehicles, depending on the design of a given locomotive and the assumptions made related to the functionality of a given solution. This article describes the PVP-20 type slip detection device used in many older electric locomotives. A proprietary measuring system was developed, enabling it to be connected to the locomotive circuit, to perform measurements in conditions of large disturbances and high voltages prevailing on the electric locomotive. Using this measuring system, the PVP-20 device was tested under operating conditions for the ability to detect slips. It has been shown that the described device is highly insensitive. Hence, we propose our concept for solving this problem.
