Solution to Morgan’s problem. (English) Zbl 0656.93018

The authors present necessary and sufficient conditions for existence of a decoupling feedback \(u=Fx+Gv\) for a time-invariant system \(\dot x=Ax+Bu\), \(y=Cx\), with A invertible, B monic, and C epic matrices. The conditions are given in terms of simple inequalities between the integers of dual Morse lists \(I_ 2\) and \(I_ 4\).
