Explanation:
Feedback is an essential component of a control system. It is the process of returning a part of the output signal to the input of a system to regulate or control the system's operation. Feedback can be positive or negative, depending on whether it amplifies or reduces the error signal.
There are two types of feedback - positive feedback and negative feedback. In positive feedback, the output signal reinforces the input signal, leading to instability and oscillation. In contrast, negative feedback reduces the error signal and stabilizes the system.
The correct answer to the given question is option 'C,' which states that feedback reduces the error and the sensitivity of the system to parameter variation. Let us understand this in detail:
1. Reduces the error:
Feedback reduces the error in the system by comparing the actual output with the desired output and adjusting the input signal accordingly. This process is known as closed-loop control, where the output signal is fed back to the input to minimize the error signal.
2. Reduces sensitivity to parameter variation:
In a control system, the parameters of the system may vary due to various reasons such as temperature, load, and aging components. These parameter variations can affect the system's performance and stability. However, feedback reduces the sensitivity of the system to parameter variation by adjusting the input signal based on the output signal. This way, even if the parameters vary, the system can adjust and maintain stability.
Conclusion:
In conclusion, feedback is an essential component of a control system that reduces the error and sensitivity of the system to the parameter variation. Negative feedback is the preferred type of feedback that stabilizes the system and maintains its performance.
