Assertion (A): Practical systems must be closed loop system.Reason (R)...
Explanation: Practically systems used must be linear to avoid error, ease of calibration and also to get accurate results but the systems used are non-linear to avoid the error due to the linearity they are approximated.

Assertion (A): Practical systems must be closed loop system.Reason (R)...
Assertion (A): Practical systems must be closed loop systems.
Reason (R): This is due to the fact that closed-loop systems are least affected by parameter variations, stable, higher bandwidth, linear, and have a faster response.
The correct answer is option 'A', which means that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
Explanation:
What is a closed-loop system?
In control systems, a closed-loop system, also known as a feedback control system, is a system where the output of the system is fed back and compared with the desired input to generate an error signal. This error signal is then used to adjust the system's parameters or inputs to minimize the error and achieve the desired output.
Why must practical systems be closed-loop systems?
Practical systems must be closed-loop systems due to several advantages they offer over open-loop systems:
1. Stability: Closed-loop systems are inherently stable as feedback is used to regulate the system. The feedback loop helps to compensate for disturbances and uncertainties in the system, ensuring stable operation.
2. Robustness: Closed-loop systems are less affected by parameter variations. Since the feedback loop continuously adjusts the system parameters based on the error signal, it can compensate for changes in the system's dynamics, ensuring robust performance even in the presence of uncertainties.
3. Bandwidth: Closed-loop systems typically have a higher bandwidth compared to open-loop systems. The feedback loop allows for faster response times, enabling the system to track and respond to changes in the input signal more effectively.
4. Linearity: Closed-loop systems can provide linear response characteristics. By adjusting the system parameters based on the error signal, the closed-loop system can maintain linearity and accurately reproduce the desired input-output relationship.
5. Speed of response: Closed-loop systems can achieve faster response times compared to open-loop systems. The feedback loop allows for immediate adjustments to the system's parameters, enabling rapid corrections and faster tracking of the desired output.
Conclusion:
Practical systems must be closed-loop systems because they offer stability, robustness against parameter variations, higher bandwidth, linearity, and faster response times. These advantages make closed-loop systems more suitable for real-world applications where accuracy, stability, and responsiveness are crucial. Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.

The correct answer is option 'A', which means that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
