Abstract :
A model reduction method for stable delay systems under L2 optimality is introduced in this paper. The reduced models may take the form of either a stable finite dimensional system or a delay system with reduced order finite dimensional part. Based on the Routh parametrization of stable systems, the two cases are studied under a unified framework of unconstrained optimization. Numerical examples are used to illustrate the effectiveness of the proposed method
