This paper proposes a control strategy for active lateral secondary suspension that uses preview data. Based on a derived analytical model a model predictive controller (MPC) is implemented. The influence of the track ahead upon carbody lateral dynamics is considered explicitly. The controller developed is applied to a full-scale rail vehicle model. Ride comfort is evaluated according to EN 12299. Multibody simulations show that on tracks with small radius curves there is a significant increase of continuous ride comfort.

摘要

This paper proposes a control strategy for active lateral secondary suspension that uses preview data. Based on a derived analytical model a model predictive controller (MPC) is implemented. The influence of the track ahead upon carbody lateral dynamics is considered explicitly. The controller developed is applied to a full-scale rail vehicle model. Ride comfort is evaluated according to EN 12299. Multibody simulations show that on tracks with small radius curves there is a significant increase of continuous ride comfort.
