🔍 Key Concepts

• proportional control – output is directly related to the size (magnitude) of the error at that instant • integral control – output depends on the accumulated (past) error over time, tends to eliminate steady‑state offset but responds more slowly • derivative control – output depends on the rate of change (slope) of the error, tends to react to how fast the error is changing

💭 Think About

• Look at figure B and ask: Is the controller reacting mainly to the size of the error, to the buildup of error over time, or to how fast the error is changing? • Does the response in figure B show overshoot being reduced and the system anticipating changes, or does it mainly remove steady‑state error after some delay? • Compare figure B to the ‘basic’ proportional response (usually in figure A); what extra behavior is added or removed in B?

✅ Before You Answer

• Check whether there is a steady‑state offset (a small final error that remains) or if the output eventually lines up exactly with the setpoint. • Check if the response in figure B shows a faster reaction to changes but less steady‑state accuracy, which is characteristic of derivative action. • Check whether the waveform in B looks like a simple scaled version of the error (proportional), an effect that grows with time when error persists (integral), or a response that is strong when the error is changing quickly and weaker when the error is steady (derivative).
