Abstract

It is well-known that there exists a critical control weighting parameter which results in an unstable controller design if the uncontrolled system is unstable or nonminimum phase and a single stage cost functional is used. The purpose of this note is to show that the determination of this parameter reduces to solving a root-locus problem.
