The PID Controller is a widely-used tool for controlling output such as velocity, temperature, and position. This article will provide an introduction to the PID terms and an example control system, as well as a chance to tune a PID controller.
The PID controller is every where - temperature, motion, flow controllers - and its available in analog and digital forms. Why use it? It helps get your output (velocity, temperature, position) where you want it, in a short time, with minimal overshoot, and with little error. In many applications the PID controller can do the job - but as usual, with compromises. After a short intro to the PID terms and an example control system, you'll get a chance tune a PID controller.
