Chapter1 Introduction Iintroducethebasicprinciplesofcontroltheoryinaconciseself-studyguide.Iwrote this guide because I could not find a simple, brief introduction to the foundational concepts. IneededtounderstandthosekeyconceptsbeforeIcouldreadthestandard introductory texts on control or read the more advanced literature. Ultimately, I wanted to achieve sufficient understanding so that I could developmyown line of researchoncontrol inbiological systems. This tutorial does not replicate themany excellent introductory texts on control theory. Instead, I present each key principle in a simple and natural progression through the subject. Theprinciples buildoneachother tofill out thebasic foundation. I leave all the detail tothoseexcellent textsandinsteadfocusonhowtothinkclearlyaboutcontrol. I emphasizewhy thekeyprinciplesare important, andhowtomake themyourown toprovideabasisonwhich todevelopyourownunderstanding. I illustrateeachprinciplewithexamplesandgraphics thathighlightkeyaspects.
