High speed technology may benefit from the acquisition of smart know-how from the automotive and aerospace sectors. In particular in the automotive sector the application of semi-active magneto-rheological (M-R) dampers has been successfully tested. Application of M-R technology and more generally of semiactive system on rail systems is documented and it is still confined to a limited number of known examples. However there is a growing interest for these kinds of solution which represents a good trade-off between the performance of a fully active system and the reliability assured by passive ones. In this paper, the application of controlled dampers to the secondary suspension stage of a railway vehicle has been used as benchmark to verify the performances of different control techniques. Centralized control system seems to be more performing especially when different control approaches are applied in a synergic way. On the other hand SISO controllers such as the Sky-Hook damper are much simpler to implement and exhibit a very robust behaviour. In both cases the achieved results are quite attractive. Currently authors are evaluating to further tests robustness and performance both with more sophisticated models (considering vehicle car-body flexibility and more sophisticated models of actuators and sensors) and experimental activities in the MDM laboratories of Pistoia, Italy.
