Which of the following is a key advantage of a PID controller in control systems?
Show Hint
- Reduces steady-state error
- Increases oscillation
- Decreases system stability
- Eliminates feedback
The Correct Option is A
Solution and Explanation
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.
