What is PID?
This “What is PID?” video is the second part of the Closed Loop System series. It begins with the basic PID definition, then uses an electronic PID controller to explain feedforward control, PI control, and P&ID concepts. The example system is a robot arm position‑control circuit that demonstrates proportional, derivative, and integral behavior in a real closed‑loop application.
