“…Therefore, many efforts have been devoted to limiting the slip/skid between the wheel and the rail [8]- [10]. Both direct and indirect re-adhesion control methods have been proposed to limit the slip within a predefined threshold [11]- [14]. The main demerit of these traditional re-adhesion methods is that the traction capability is not fully utilized.…”

Torsional Vibration Suppression in Railway Traction Drives

Torsional vibrations phenomena are self-excited vibrations that occur in the wheelset of railway powertrains due to the counter-phase oscillation of both wheels. Long-lasting events of this type may lead to the catastrophic failures. Therefore, torsional vibration suppression and mitigation methods have drawn significant attention from the railway industry in the recent few years. Conventional vibration suppression methods reduce motor torque once the oscillation is detected. However, this can result in trip delays. Design of methods which do not compromise the traction capability is challenging. This paper proposes a novel torsional vibration suppression method using a Proportional-Resonant (PR) controller. The proposed method is insensitive to mechanical drive-train parameter variation neither requires adding new sensors to the wheelset. The method requires previous knowledge of the natural frequency of the wheelset torsional mode but this significantly reduces the implementation complexity suffered by other anti-vibration methods. Furthermore, the method will be shown to provide reduced sensitivity to slip velocities and wheelrail conditions.INDEX TERMS Railway traction drives, torsional vibrations, slip-stick phenomenon, slip control, fieldoriented control, proportional-resonant controller.

“…The traction control system, also known as an adhesion or anti-slip control system is essential for the operational efficiency and reliability in these systems. A pattern-based slip control method has been applied and modified by Doh-Young et al [12]. Anti-slip control based on a disturbance observer was proposed by Ohishi et al [13].…”

In recent decades, advanced power-electronics-based control techniques have been widely used to electric drives for the traction of modern locomotives. However, the dynamic response of such locomotives under transient conditions due to external perturbations has not been fully investigated. In this work, an integrated dynamic model for a typical Co-Co locomotive/track system is developed to provide predictive simulations of the motion and forces transmitted throughout the whole locomotive dynamic system. The model integrates a 2D longitudinal-vertical locomotive structural vibration model, wheel/rail contact mechanics using Polach's creep force model, a simplified dynamic traction model and a fuzzy logic creep controller to simulate the transient response to a change in friction conditions. It is found that the proposed fuzzy logic controller has the advantage over a PI controller in terms of achieving higher tractive force under transient contact conditions.

“…Проблемою поліпшення зчіпних властивостей локомотивів займаються й інші відомі фірми: Siemens, Hitachi, Ansaldo, General Motors та інші [9][10][11][12]18]. В усіх цих розробках дуже багато схожого з вітчизняними і принципових розходжень у підходах майже не має, але для регулювання сили тяги колісних пар використовуються досить складні алгоритми на основі спостереження за швидкістю прослизання.…”
