  • Abstract
    This correspondence describes a balancing technique of model reduction which is characterized by exactness at zero frequency. Various interesting properties and error bounds of the reduced-order model are derived in a rigorous manner. A critical comparison is made to Moore´s reduced model (1981) obtained by direct truncation. An illustrative numerical example is included
