An improved suboptimal model reduction for singular systems

An improved suboptimal model reduction for singular systems is proposed. The proposed method is based on Silverman-Ho algorithm as in Wang et al. (2004). A full parametrization of reduced-order models is provided unlike the technique of Wang et al. (2004) where in only partial parametrization is presented. The proposed method is illustrated by a numerical example and is compared with the method of Wang et al. (2004).
