1Introduction
This book aims to introduce digital control systems via practical applications. Therefore, we will briefly introduce the system and control theory concepts in this chapter. Then, we will emphasize how this book differs from the ones in literature. Besides, we will summarize the concepts to be explored in the book. Hence, the reader will have necessary background for the following chapters.
1.1 What is a System?
A system can be defined as the combination of parts to carry out a specific task. Let us pick the Pololu Zumo robot (https://www.pololu.com/product/2510/) in Figure 1.1. This is a system composed of four main parts as chassis, motors, tracks with sprockets, and battery. When energy is fed to the motors, they move the chassis via rotating sprockets.
We can add two more modules to the Zumo robot as a control unit (such as microcontroller) and reflectance sensor. These modules can be used to add autonomy to the robot such that it can follow a line drawn on ground. To do so, we will need a “control” action. Let us introduce it next.
1.2 What is a Control System?
Control is the act of producing a desired output for a given input. The control system is used for this purpose. For our Zumo robot, our aim is following the line. Hence, the robot system should be guided by a control system to follow the line. To be more specific, the control system should get the reference input signal (as position of the line) and current position of the robot from the reflectance ...
