New analytical right\/left inverses of polynomial matrices are introduced, including the so\-called \? \-inverses, \?\-inverses and, in particular, S\-inverses, the latter providing the most general tool for the design of various polynomial matrix inverses. The pplicationoriented problem of selecting stable inverses is also solved. Applications in inverse\-model control, in particular robust minimum variance control, are exploited, and possible applications in signal transmission\/recovery in various types of MIMO channels are indicated."]
