Pbkp_redictor-based stabilization of discrete time-varying input-delay systems

Abstract:

This paper adapts some literature results on stabilizing discrete time-varying input delay systems to the case of having a pbkp_redictor-based controller. The objective of the paper is showing that the incorporation of pbkp_redictors to the referred results is relatively simple and, by means of such pbkp_redictors, robustness against delay mismatch in the input channel may be improved. In this way, larger delay variation margins are proved with pbkp_redictors when compared to standard memoryless state feedback, as intuitively expected, due to the extra past information available. © 2011 Elsevier Ltd.
