Model reduction of linear time-varying systems with application for moving loads
In this paper we consider different model reduction techniques for systems with moving loads. Due to the time-dependency of the input and output matrices, the application of time-varying projection matrices for the reduction offers new degrees of freedom, which also come along with some challenges. This paper deals with both, simple methods for the reduction of particular linear time-varying systems, as well as with a more advanced technique considering the emerging time derivatives.
