Flexible time-response matching in discrete model reduction

T. Nigel Lucas

Research output: Contribution to journalArticlepeer-review


A simple way to match the time responses of the full- and reduced-order models at arbitrary sampling points is given for discrete-time systems. It is seen to be a natural extension of the Padé methods and is particularly useful in oscillatory systems. An example illustrates the technique.
