A structural analysis of the pole shifting problem. (English) Zbl 0768.93029
Summary: Pole assignability and stabilizability problems are investigated qualitatively. Both problems are first formulated algebraically and then translated to a structural setting via graph-theoretic formulations. Graphical sufficient conditions concerning the closed-loop system digraph which determine pole assignable and stabilizable structures are developed.
