Abstract :
The model reduction problem is formulated in terms of the minimisation of a quadratic scalar cost function. The l2-optimal reduced numerator for computation would require a Gram matrix inversion. The authors show that this inversion can be avoided owing to an orthogonalisation process which is easily derived from the classical stability Routh table.
