Adaptive structures are equipped with sensors and actuators to counteract deformations caused by external loads. Concerning railway bridges, previous work has shown that active vibration damping allows extend the service life. Trains as loads represent decisive influencing factor for bridge be taken into account when applying model-based control concepts. This article proposes a state disturban...
