Singular ( J, J' )-lossless factorization for strictly proper functions
XIN XIN, Hidenori Kimura · International Journal of Control · 1994
Singular (J, J')-lossless factorization for strictly proper functions is studied. The method of infinite zero compensation derived by Copeland and Safonov is used to extend the results of Kimura to singular systems. Since (J, J')-lossless factorization contains both inner–outer factorization and Wiener–Hopf spectral factorization as special cases, the results obtained here unify previous results on singular factorization problems.
