The loop transfer function of controller Gc(s) is :
- a)1+0.1s/s
- b)-1+0.1s/s
- c)–s/s+1
- d)s/s+1
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The loop transfer function of controller Gc(s) is :a)1+0.1s/sb)-1+0.1s...
Answer: a
Explanation: The transfer function of the controller is 0.1s+1/s
Gc(s) = 0.1s+1/s.
Explanation: The transfer function of the controller is 0.1s+1/s
Gc(s) = 0.1s+1/s.

Understanding the Loop Transfer Function of Gc(s)
The loop transfer function Gc(s) plays a crucial role in control systems. Let's analyze the given options and identify why option 'A' is the correct answer.
Option A: 1 + 0.1s
- This function represents a first-order lag compensator.
- The term "1" signifies the system's unity gain at low frequencies.
- The term "0.1s" indicates a proportional gain that introduces a zero, enhancing system response by improving stability and transient performance.
Other Options for Comparison
- Option B: -1 + 0.1s
- This option contains a negative constant, which is generally not suitable as a transfer function because it can lead to instability or an improper system response.
- Option C: -s/(s + 1)
- The presence of a negative numerator suggests potential instability, making it unsuitable for a controller.
- Option D: s/(s + 1)
- This is a simple proportional controller suggesting a gain but lacks a zero, which is vital for enhancing the performance of the controller.
Key Takeaways
- Importance of Zero: Option A introduces a zero, which is essential for improving transient response without compromising stability.
- Stability: A proper loop transfer function must ensure system stability; option A does this effectively.
- Performance Enhancement: The form 1 + 0.1s ensures that the system can respond adequately to changes while maintaining stability.
In conclusion, option 'A' is the most suitable choice for the loop transfer function Gc(s) due to its ability to enhance stability and performance in control systems.
