A linear time-invariant system with commensurate delays is considered. The system is characterized by two matrices

and

over
![R[d]](/images/tex/3197.gif)
(polynominal in the delay operator

). It is assumed that the pair (

) is reachable over the ring
![R[d]](/images/tex/3197.gif)
. A constructive procedure is derived which, for any initial conditions, finds a solution to system equations such that both the control and the state trajectory become zero identically after some finite time.
