Question

Which of the following is a key advantage of a PID controller in control systems?

• A. Reduces steady-state error
• B. Increases oscillation
• C. Decreases system stability
• D. Eliminates feedback

Hint:

Tune PID parameters for optimal control in dynamic systems.

Answer 1

The Correct Option is A

Step 1: Understand PID controller
PID (Proportional-Integral-Derivative) controllers adjust system output for stability and accuracy.
Step 2: Evaluate options
Reduces steady-state error: Integral term corrects error over time.
Increases oscillation: Incorrect, PID reduces oscillation.
Decreases system stability: Incorrect, PID enhances stability.
Eliminates feedback: Incorrect, PID relies on feedback.
Step 3: Select advantage
Key advantage is reducing steady-state error via integral action.
