Which of the following is the advantage of a closed loop control system

Electrical Engineering XYZ MCQs

Which of the following is the advantage of a closed loop control system:

1. The closed loop systems are less affected by noise
2. The closed loop systems are accurate
3. Both of the above
4. None of the above

Correct answer: 3. Both of the above

Explanation:

1. Closed loop systems are less affected by noise: In a closed loop control system, there is a feedback mechanism that continuously monitors the output and adjusts the input accordingly to maintain desired performance. This feedback helps in reducing the impact of external disturbances or noise on the system. By continuously comparing the actual output with the desired output, any deviations caused by noise can be corrected, resulting in a more stable and reliable system.
2. Closed loop systems are accurate: Due to the feedback mechanism, closed loop control systems tend to be more accurate compared to open loop systems. The continuous monitoring and adjustment based on feedback ensure that the system maintains desired performance despite variations in external conditions or disturbances. This accuracy is especially important in applications where precise control is required, such as in industrial processes, robotics, aerospace, etc.

Therefore, both of the statements provided in the MCQ are advantages of closed loop control systems.
