In order to improve the lateral riding quality of railway vehicles, various type of Full-Active or Semi-Active Suspension Systems have been developed and in use. Semi-Active System is announced more useful in energy saving and fail-safe than Full-Active System; but the efficiency of Semi-active System is half of Full-Active System and is none in the crossing section. So we have been researching new control method to improve the skyhook Semi-Active System. One of our trials is a Collaboration Control of Semi-Active damper and Short Stroke Actuator in series connection. As a result, we have achieved the decrease of lateral acceleration to the level of Full-Active System with small energy.
