✦ Synopsis

The problem oj'approximating an original rational matrix by means oj'a rational matrix of lower order according to the L,-norm criterion is considered. In particular, a compact ,form of the necessary conditions,jiw optimal@ is derived, which may be considered as the extension to the multivariable case of the interpolation conditions valid in the scalar case. On the basis of' this ,form, an iterative numerical technique to jind the optimal approximating model is suggested.

The L,-optimal reduced model retaining a given number of poles of the original system is determined in an eficient way. In particular, an expression for evaluating the minimum of the impulse response error norm for any choice of retained poles is derived in terms of the original system parameters, w

The iron and steel industry is a large energy user in the manufacturing sector. Carbon dioxide from the steel industry accounts for about 5-7% of the total anthropogenic CO 2 emission. Concerns about energy consumption and climate change have been growing on the sustainability agenda of the steel in
