Inversion of singular systems
Shubin Tan, Joos P. L. Vandewalle · IEEE Transactions on Circuits and Systems · 1988
A method for inverting square singular systems is presented. The construction explores the possibility of singular-system representation, and provides a simple and closed form for the constructed inverse. One important property is that the minimality of the inverse (in the sense of Verghese) is equivalent to that of the original system.>
