Explain the difference between a control loop's steady-state error and transient error.

Explain the difference between a control loop's steady-state error and transient error.

• A. Steady-state error is the residual error after the loop settles; transient error is the temporary deviation during a disturbance or setpoint change.
• B. They are the same thing.
• C. Steady-state error is the initial deviation after a setpoint change; transient error persists after settling.
• D. Transient error is the residual after settling; steady-state is temporary.

Answer: (C)
