Abstract :
In an earlier note it was shown that designing a nonstrictly proper output feedback compensator using a model that neglects parasitic elements might lead to an unstable closed-loop system even when the neglected modes are asymptotically stable. The purpose of this note is to show that this instability phenomenon might take place even when the reduced-order design model is strictly proper.
