Solution of the static-state feedback decoupling problem for linear systems with two outputs. (English) Zbl 0566.93010
We give for linear systems with two outputs a necessary and sufficient condition for the solvability of the restricted decoupling problem (RDP) in terms of some structural invariants. A geometric characterization is also given which provides the least dynamical extension needed when RDP is not solvable.
