The Procedure of Designing a Control System

[dude4jesus]

Nice job....what he means is that once you have modeled your physical system (this is usually a differential equation), then you can modify that differential equation to suit your needs or achieve your desired output. The modification part is done by a controller and usually you have a feedback loop just measure your actual output against your desired output to make necessary changes.
