The present work focused on the application of innovative damping technologies in order to improve railway vehicle performances in terms of dynamic stability and comfort.As a benchmark case-study,the secondary suspension stage was selected and different control techniques were investigated,such as skyhook,dynamic compensation,and sliding mode control.The final aim was to investigate which control schemes are suitable for optimal exploitation of the non-linear behavior of the actuators.The performance improvement achieved by adoption of the semi-active dampers on a standard high-speed train was evaluated in terms of passenger comfort.Different control strategies have been investigated by comparing a simple SISO (single input single output) regulator based on the skyhook damper approach with a centralized regulator.The centralized regulator allows for the estimation of a near optimal set of control forces that minimize car-body accelerations with respect to constraints imposed by limited performance of semi-active actuators.Simulation results show that best results is obtained using a mixed approach that considers the simultaneous applications of model based and feedback compensation control terms.
