            Abstract : 
Recent studies have shown that, for a given system ¿, the possibilities for pole assignment through internally stable output-feedback control configurations depend on certain integer invariants, related to the number of unstable poles, the number of unstable zeros, and the number of zeros at infinity of the system ¿. The present note provides a qualitative discussion of the conceptual and of the intuitive origins of these results.
