Interference of active comfort and wheelset stability controllers
KTH railway group intends to revive the old two-axle rail vehicle concept and reintroduce it as a modern passenger vehicle with the operational speed up to 200 km/h. Two-axle rail vehicles are cheap, light and easy to maintain but have different running limitations. Different active suspension technologies can be used to improve on these limitations. One challenge with introducing different active suspension systems on vehicles with just one level of suspension is the high risk of active systems interfering in each other’s objectives. This study investigates the interference of active comfort and wheelset stability controllers.
