Abstract

This paper introduces a control strategy for active secondary suspension based on Model Predictive Control. The influence of the track irregularities and track layout upon carbody lateral and vertical dynamics is considered explicitly. The developed controller is applied to a full-scale rail vehicle model. Ride comfort is evaluated according to EN 12299. Multibody simulations show that on a realistic high-speed track there is a significant increase of ride comfort.
