Abstract :
In this paper, we propose an algorithm for model order reduction of large scale systems that can be described by delayed differential equations. The algorithm is based on the combination of a Laguerre expansion technique for the delays and higher order Krylov subspaces. Pertinent numerical results validate the accuracy and efficiency of the proposed model order reduction approach.
