The paper contains details of a research conducted to investigate the applicability and requirements of actuators in the implementation of active solid axle wheelset control and the effect of actuator dynamics on the whole control system. Research is based on the use of Electric-Mechanical (EM) actuators and it is focused on two main issues, both of which will be affected by vehicle configurations, operational speed and track features such as curvatures and irregularities. One is the effect of the active controller on the stability and performance of the overall train suspension system when actuated. The other is the power and energy requirement of the actuators. Furthermore, optimization of actuator parameters to achieve higher effectiveness is also addressed.
