Abstract
A new approach to the row by row decoupling of singular systems via st ate feedback and regular input transformation is presented. The propos ed method is based on the matrix fraction description of the system an d is an extension of the frequency domain method for strictly proper s ystems. The solvability condition of the problem is readily obtained f rom the 'numerator' matrix of a coprime and column reduced matrix frac tion description of the given system. Pole placement and decoupling is also considered, and the characterization of the fixed poles is given . (C) 1997 Elsevier Science Ltd.
