Robust control and approximation in the chordal metric

Conference paper
Part of the Lecture Notes in Control and Information Sciences book series (LNCIS, volume 183)


The chordal metric on SISO transfer functions (possibly unstable and infinite-dimensional), which generates the graph topology, is considered as a measure of robustness for stabilizing controllers. Connections with approximation are also explored.
