A thermostat. It measures the room temperature, compares it to your goal, and adjusts the heater accordingly. This is Feedback Control . 2. The Components of a Loop To understand any control system, visualize this circle:

It’s a mathematical "filter." You put an input in, and the transfer function tells you how the output will be shaped. Fundamentals of Control Theory: An Intuitive Ap...

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. A thermostat

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. A stable system settles; an unstable one oscillates

You set a timer on a toaster. It toasts for 2 minutes regardless of whether the bread is frozen or already burnt. No feedback.

In control theory, we represent parts of a system as a .
