Abstract :
State-space formulas for all key spectral factorizations appearing in the discrete-time H2/H∞ optimization are summarized. The factorization problems are categorized into three groups. Solutions are constructed by finding special coprime factors of a given transfer matrix using the associated discrete algebraic Riccati equation. Solution procedures for the three groups are in general the same, which may lead to yield to a unified approach
