Question

A temperature control system is usually very sluggish. To improve its dynamics:

• A. a PI controller can be used
• B. an I controller can be used
• C. PID controller with large I and negligible D can be used
• D. PD controller can be used

Hint:

Use PD controller to enhance transient response and speed up sluggish systems.

Answer 1

The Correct Option is D

Sluggish systems typically have slow response and poor dynamics. To improve transient performance, a Proportional-Derivative (PD) controller is used as it increases system responsiveness and adds damping, improving the speed of response without affecting steady-state error significantly.
