D. Kavranoglu et Sh. Al-amer, New efficient frequency domain algorithm for H-infinity approximation withapplications to controller reduction, IEE P-CONTR, 148(5), 2001, pp. 383-390
New frequency domain computational schemes for the weighted and unweighted
H-infinity norm system approximation problems are introduced. The schemes a
re applicable in both continuous and discrete-time cases. The new algorithm
is used to obtain reduced order controllers for a well known control probl
