For instance, transfer functions of descriptor systems and delay systems fall into this family. We focus on the case where the middle factor is very large. We propose a subspace projection method to obtain approximations of the function H where the middle factor is of much smaller dimension. The \\(H\\)-infinity norms are computed for the resulting reduced functions, then the subspaces are refined by means of the optimal points on the imaginary axis where the largest singular value of the reduced function is maximized. The subspace method is designed so that certain Hermite interpolation properties hold between the largest singular values of the original and reduced functions. This leads to a superlinearly convergent algorithm with respect to the subspace dimension, which we prove and illustrate on various numerical examples.<\/p>\n <\/div>\n <\/div>\n\n \n <div

For instance, transfer functions of descriptor systems and delay systems fall into this family. We focus on the case where the middle factor is very large. We propose a subspace projection method to obtain approximations of the function H where the middle factor is of much smaller dimension. The \\(H\\)-infinity norms are computed for the resulting reduced functions, then the subspaces are refined by means of the optimal points on the imaginary axis where the largest singular value of the reduced function is maximized. The subspace method is designed so that certain Hermite interpolation properties hold between the largest singular values of the original and reduced functions. This leads to a superlinearly convergent algorithm with respect to the subspace dimension, which we prove and illustrate on various numerical examples.<\/p>\n <\/div>\n <\/div>\n\n \n <div
