This paper investigates the performance of coprime factor based controller reduction methods. We show that under some mild conditions closed-loop performance bounds can be derived for observer-based controllers. The results in this paper lay a mathematical foundation for using coprime factor controller reduction methods in certain classes of controller reduction problems.
