Leang San Shieh, Fan Chang, Bayliss C. McInnis · IEEE Transactions on Automatic Control · 1986
A state-space technique is developed for finding the block partial fraction expansion of an irreducible right matrix fraction description with distinct and/or repeated block poles. The developed method is the generalized version of the existing methods which consider only distinct block poles.
