Non-descriptor dynamic output feedback ESPR controller design for continuous-time descriptor systems

In this article, the non-descriptor output feedback controller for extended strictly positive real (ESPR) control problem of continuous-time descriptor systems is proposed. More precisely, the proposed controller will achieve the ESPR property for the closed-loop transfer matrices while the regularity, impulse immunity and stability of the closed-loop system can be guaranteed. Furthermore, the desired controller is in non-descriptor form and can be carried out by solving a set of linear matrix inequalities; thus it is realisable and efficiently computable.
