Strictly positive real and conic system syntheses using observers

摘要

This paper studies how linear time-invariant systems may be transformed into strictly positive real or interior conic systems using observers. The transformation into a strictly positive real system is achieved for a broader class of systems than in previous work, including those that are uncontrollable or unobservable. The transformation into an interior conic system using an observer is a novel contribution. Both methods are illustrated in a numerical example.
