Introduction to PID control

Did you know that an insulin pump for diabetics, a room air conditioner, and a drone have something in common? They all use control engineering to keep a specific variable, such as glucose level, temperature, or altitude, at a desired value. In this video, we explore the famous Proportional, Integral, Derivative control algorithm, known as PID.
To intuitively understand PID control, we use a mechanical simile: the mass-spring-damper system. We explore concepts such as error, disturbance, and control action, and how to adjust these elements to keep mass at a reference position. We also explain how the accumulation of error over time, represented by the error integral, forms proportional-integral (PI) control, and how viscous friction, or error derivative, helps prevent overshoot.
