Question

In a Proportional-Integral-Derivative (PID) controller

• A. The proportional term introduces damping to the system.
• B. The derivative term eliminates steady-state error.
• C. The integral term improves transient response.
• D. The proportional term contributes to steady-state accuracy.

Hint:

In PID control, focus on tuning the proportional, integral, and derivative terms to achieve desired accuracy, response time, and stability.

Answer 1

The Correct Option is D

In a PID controller:
- The proportional term affects the response speed and steady-state accuracy.
- The derivative term improves stability and reduces overshoot.
- The integral term eliminates steady-state error by accumulating error over time, correcting for any bias.
Thus, the proportional term is directly responsible for steady-state accuracy.
