Strict Positive Realness for Linear Systems with Multiple Time-delays

摘要

This paper is concentrated on strict positive realness (SPR) of linear time-delay system via linear matrix inequality (LMI) technique. We present sufficient conditions via LMIs such that linear delayed system is strictly positive real. More generally, we present a memoryless state feedback controller via LMIs such that the resulting closed-loop system is SPR for a class of linear time-delay control system.
