If you poke a system, does it return to equilibrium or blow up? A stable system settles; an unstable one oscillates wildly or accelerates to destruction. Damping: Think of a door closer. Underdamped: The door swings back and forth before closing. Overdamped: The door takes forever to close.

You set a timer on a toaster. It toasts for 2 minutes regardless of whether the bread is frozen or already burnt. No feedback. Fundamentals of Control Theory: An Intuitive Ap...

The "eyes" that measure the output and feed it back to the start. 3. PID Control: The "Big Three" If you poke a system, does it return

At its heart, control theory is about making a system (the ) behave the way you want (the Reference ) by using a Controller . Underdamped: The door swings back and forth before closing

The "brain" that decides what to do based on the error. Actuator: The muscle (e.g., the car's engine or a heater). Plant: The physical system being controlled.

It’s a mathematical "filter." You put an input in, and the transfer function tells you how the output will be shaped.

"The Present." The harder you are from the goal, the harder you push. If the error is big, the response is big.
