Abstract :
This paper studies the optimal realizations of a finite-word-length (FWL) digital state-estimate feedback controller with closed-loop pole sensitivity minimization considerations. Through analysis it is shown that the pole sensitivity measure is coordinate dependent. Structures that minimize this measure are found
