“…It can be readily shown that this configuration will be able to stabilise solid-axle wheelset and an excellent curving performance may be achieved [10,16]. The actuators may also be mounted between the vehicle body and bogie in the lateral direction to provide active ''hunting control'' [17]. A drawback of the configuration, as it will be shown later, is that the actuation force controlling the wheelset will also act directly on the body in the lateral direction and hence cause the ride quality to deteriorate.…”

“…There are other controllers that have been studied and classic control design approaches with the structure of P, PI or PID are often favoured for their structural simplicity and well-known design methods [17,18,21]. However a key issue is that this control approach normally requires a feedback of measurement such as wheel-rail deflection and angle of attack, which is very difficult to measure in practice.…”

This paper presents the recent development on active steering for railway vehicles, and carries out a technical appraisal of different actuation schemes and control approaches. It brings together the latest research activities and findings for the full active steering techniques for rail vehicles with the solid-axle wheelsets, independently-rotating wheelsets and wheel-pairs without axles, but relevant work on passive and semi-active solutions is also briefly described. Potential benefits of the use of a combination of modern control technology and mechatronic approach are evaluated, and in particular solutions for the difficult design trade-off between the stability and the curving performance are presented. Various actuation configurations are discussed, and advantages and drawbacks of those schemes are investigated. The outline design using a number of control methods is analysed, and measurement requirement and state estimation techniques essential for implementation of the active steering schemes are also explored. In addition the issue of safety criticality is highlighted and a possible approach for developing fault-tolerant systems is proposed. Overall the paper provides an authoritative assessment of the major advances in actively-steered wheels and addresses outstanding critical issues.

Experimental testing components, innovative solutions and control strategies is essential in order to increase performances, optimize efficiency and ensure a proper safety level of a railway vehicle. These tests are usually performed directly on line, thus being very expansive. In order to reduce costs and save time during the testing/analysis phase, the use of dedicated test rigs is increasing. A roller rig for testing full scale locomotives is considered in this paper. In order to investigate the influence of the roller rig dynamics on the test bench behavior in a design stage, a numerical model of the full system (including the locomotive, the roller rig and the corresponding control systems) has been developed and a parametric analysis has been carried out.
