Comprehend (C)

This chapter introduces the fundamentals of control systems, including what a control system is, how feedback generates an error signal, and how the main elements of a feedback loop are represented using block diagrams.

It serves as an entry point into control engineering and outlines the key ideas that underpin later study of controllers, actuators, system dynamics, disturbances, and closed-loop behaviour.

Chapter overview

Introduction to Control Systems presents the core language and structure used throughout control engineering. The chapter explains how a desired reference is compared with a measured output, how the resulting error is used by a controller, and how actuators and sensors fit within a closed-loop system.
