PID Control

PID control is a method used to automatically adjust a system to reach and maintain a desired target. It works by calculating the difference between the current state and the goal (the error), then applying three types of corrections: the Proportional part addresses the current error, the Integral part considers past errors to eliminate steady mistakes, and the Derivative part predicts future errors to prevent overshoot. Together, these components ensure smooth, accurate, and stable control, such as maintaining a consistent temperature or speed without manual intervention.
