Question:
The incorrect option for a Closed loop control system output is
The incorrect option for a Closed loop control system output is
Show Hint
Feedback reduces sensitivity but never makes the system completely independent of parameter variations.
Updated On: Jun 25, 2026
- Decrease the effect of noise
- Improves the overall stability
- Sensitivity is reduced
- Independent of variation in feedback parameter
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Closed-loop control systems employ feedback to improve performance and reduce sensitivity to parameter variations.
Step 1: Examine the advantages of closed-loop systems.
Closed-loop systems generally:
• Improve accuracy
• Reduce sensitivity
• Improve disturbance rejection
• Improve stability characteristics
Step 2: Analyze option (D).
The output of a closed-loop system still depends on the feedback path. Variation in feedback parameters affects system performance. Therefore the output cannot be completely independent of feedback parameters.
Step 3: Conclusion.
Option (D) is incorrect. \[ \boxed{\text{Correct Option (D)}} \]
