This paper presents a review on the fundamental performance limitations and design tradeoffs of feedback control systems, ranging from classical performance tradeoff issues to the more recent information-theoretic analysis, and from conventional feedback systems to networked control systems, with an attempt to document some of the key achievements in more than seventy years of intellectual inquiries into control performance limitation studies, as so embodied by the timeless contributions of Bode known as the Bode integral relations.
