Given a system which may not be capable of decoupling via static state feedback but is capable of decoupling via dynamic feedback, a canonical dynamic extension is constructed. It is shown that every dynamic extension contains this canonical one. Hence, the Δmix dynamics as defined by K. Wagner (1989) of the canonical extension is contained in every other dynamic extension. Following Wagner's result, the stability of this Δmix dynamics is necessary for noninteraction with internal stability. The results obtained show that in the investigation of noninteraction with stability one can assume without loss of generality that the system is capable of decoupling via static state feedback

Bilinear systems are classified into two categories: homogeneous and inhomogeneous. Sufficient conditions which ensure the global controllability of discrete-time bilinear systems are obtained by localized analysis in control variables.
