A canonical reduced form for singular time invariant linear systems
/

We consider quadruples of matrices $(E, A,B,C)$, representing

singular linear time invariant systems in the form \begin{equation}\label{c2eq1}\left .\begin{array}{rl}

E\dot x(t) &=

Ax+Bu\\ y&=Cx\end{array}\right \}\end{equation} with $E,A\in M_{p\times n}(C)$, $B\in M_{p\times

m}(C)$ and $C\in M_{q\times n}(C)$ under proportional and derivative

feedback and proportional and derivative output injection.

In this paper we present a canonical reduced form preserving the

structure of the system and provides a decomposition of the system into two independent

systems, one being a maximal regular system and the second one a minimal completely singular one.
