PID Controllers

Proportional‑integral‑derivative (PID) controllers are a widely used class of feedback control systems that are implemented in various applications, including industrial automation, robotics, and process control. They are designed to regulate the output of a system by adjusting the input based on the error between the desired and actual outputs.
How PID Controllers Work
PID controllers operate based on the principle of feedback control, where the error between the desired and actual outputs is used to adjust the input to the system. The controller continuously monitors the system's output and calculates the error signal, which is the difference between the desired output and the actual output. The controller then uses this error signal to generate a control signal that is applied to the system to minimize the error.
The three terms in the PID controller's name represent different control actions:
