“…Also, when the disturbance occurs, one side created greater torque to recover lateral displacement. Because the lateral displacement occurred close to the right side, the front wheel according to (3) showed increasing torque of right motor, and the rear wheel showed increasing torque of the left side motor. This could be shown in the Fig.…”

“…Thus, lateral restoring force control for sharp curve drive of independently rotating wheel suspension is the core technology of the low-depth urban railway system. [3][4][5][6][7] In this paper, a control of the lateral displacement restoring force for sharp curved drive of the shallow-depth subway systems is proposed. The drive torque, steering torque command were made to execute this research to increase the stable drive performance without contacting the flange in the curved-railroad.…”

-This paper presents a lateral displacement restoring force control for the independently rotating wheelsets (IRWs) of shallow-depth subway systems. In the case of the near surface transit, which has recently been introduced, sharp curved driving performance is required for the city center service. It is possible to decrease the curve radius and to improve the performance of the straight running with the individual torque control. Therefore, the individual torque control performance of the motor is the most important point of the near surface transit. This paper deals with a lateral displacement restoring force control for sharp curved driving. The validity and usefulness of the proposed control algorithm is verified by experimental results using a small-scale bogie system.

“…These are then used to provide traction, wheel guidance and stability control. The motors can be externally mounted and connected to the wheelset through a gearbox (Pérez et al [137], Liang et al [139,140], Ahn et al [141], Lu et al [142] and Farhat et al [98,143]) as shown in Fig. 30 or embedded inside the wheels (Mei et al [144], Ji et al [145] and in the 'Next Generation Train' project in [124], [146][147][148][149]).…”

Since the concept of active suspensions appeared, its large possible benefits has attracted continuous exploration in the field of railway engineering. With new demands of higher speed, better ride comfort and lower maintenance cost for railway vehicles, active suspensions are very promising technologies. Being the starting point of commercial application of active suspensions in rail vehicles, tilting trains have become a great success in some countries. With increased technical maturity of sensors and actuators, active suspension has unprecedented development opportunities. In this work, the basic concepts are summarized with new theories and solutions that have appeared over the last decade. Experimental studies and the implementation status of different active suspension technologies are described as well. Firstly, tilting trains are briefly described. Thereafter, an indepth study for active secondary and primary suspensions is performed. For both topics, after an introductory section an explanation of possible solutions existing in the literature is given. The implementation status is reported. Active secondary suspensions are categorized into active and semi-active suspensions. Primary suspensions are instead divided between acting on solid-axle wheelsets and independently rotating wheels. Lastly, a brief summary and outlook is presented in terms of benefits, research status and challenges. The potential for active suspensions in railway applications is outlined.

“…4 Stability control simulation and experimental research by 1/5 scale independently driven wheel test rig was implemented based on yaw feedback control. 5,6 Although several active control schemes have been proposed for independently rotating wheels, some fundamental problems still need to be solved satisfactorily. One of the key issues for the control system is the measurement difficulty in the feedback signal.…”

As the well-known difficulties are that feedback signals are not easy and economical measurement in practice for active control, this paper presents a study of state estimation for active control of independently rotating wheels (IRW) based on observers. The reduced-order observer and high-order sliding mode observer are used to provide reliable and accurate estimations of the wheel pair state and track curvature using practical sensors. This proposed method uses less sensors than the one of previous studies. Furthermore, lateral accelerator and yaw velocity sensors (gyros) are economical and available for active steering and stability control system to obtain the required feedback signals. The wheels' relative rotational speed, track curvature and yaw angle of wheelsets are the feedback signals for IRW active control approach. Computer simulations are used to verify the effectiveness of proposed methods and assess control performance in stability and negotiation.
