🔍 Key Concepts

• Feedback control modes in automatic control systems (proportional, integral, derivative) • How time in error (not just size of error) affects the control signal • Difference between correcting based on accumulated past error vs. instantaneous error vs. rate of change of error

💭 Think About

• Ask yourself: which control mode responds more strongly the longer the process variable has been away from the setpoint, even if the error size stays the same? • Which option describes a control action based on the history/accumulation of error over time, rather than just the present error or how fast it’s changing? • Consider how each action (proportional, integral, derivative) is drawn on a basic control block diagram and what its input signal mathematically represents.

✅ Before You Answer

• Verify which action is associated with the accumulated (summed) error over time. • Double‑check which action responds to instantaneous error only and which responds to rate of change of error so you can rule those out. • Confirm that the correct choice is the one whose definition includes the idea of time duration of the error, not just its magnitude or its rate of change.
