Abstract
In this paper, we propose to define the transfer function of a system in a new way, namely as a semi-cancellable fraction (SCF), i.e., a fra ction in which unstable pole-zero cancellations are not allowed. Withi n this nerv framework, it is possible to be rigorous and coherent in d ealing with the stabilizability of a system from an input-output viewp oint, as opposed to recent papers focusing on the stabilizability of i nfinite dimensional input-output systems.
