Question
Name the components of a control system.
Answer
**Sensor** → **ADC** → **microprocessor** → **actuator** → **feedback path** back to be measured again.
Question
Open loop or closed loop?
Answer
**Open** acts without checking the result (a heater on a timer). **Closed** measures the result and acts on the **error** (a thermostat).
Question
What does feedback add?
Answer
The ability to correct **disturbances nobody predicted**. An open loop follows a plan; a closed loop pursues a goal.
Question
What is hysteresis?
Answer
A deliberate gap between the switch-on and switch-off points, so the actuator does not cycle constantly around the target and wear out.
Question
Why is control software real-time?
Answer
A correct answer **too late is a wrong answer** — braking 200 ms late is a crash. It must respond within a guaranteed time, not an average one.
