Abstract
Summary:We study the tracking control of linear delay systems. It is based on an algebraic property named $\pi $-freeness, which extends Kalman’s finite dimensional linear controllability and bears some similarity with finite dimensional nonlinear flat systems. Several examples illustrate the practical relevance of the notionKeywords
