best explanation to how PID works: With examples and simulation Java code

Imagine you're driving a car on a winding road. As you steer, speed up, or slow down, you're constantly making adjustments to stay on track. Sometimes you need to react quickly to a sharp turn, while other times, you make gentle corrections to keep your ride smooth. This constant balancing act is similar to what a PID controller does in various systems.

PID stands for Proportional-Integral-Derivative, and it's a control mechanism widely used in engineering and industrial applications to keep systems running smoothly and efficiently. From cruise control in cars to temperature regulation in ovens, and even the stabilization of drones, PID controllers are everywhere, quietly working behind the scenes to make sure things behave as they should.

In this book, we will explore the fascinating world of PID control in simple, easy-to-understand language. We will break down the complex concepts and show how they relate to everyday experiences. You don't need to be a math wizard to understand PID control.
