Question

Arrange the following elements of a feedback control loop in the correct order: (A) Actuator (B) Error detection (C) Controller (D) Feedback sensor Choose the correct answer from the options given below:

• A. (B), (C), (A), (D)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (C), (B), (D), (A)

Hint:

In a feedback control loop, the process starts with error detection, followed by control, actuator adjustment, and feedback for continuous correction.

Answer 1

The Correct Option is A

Step 1: Understanding Feedback Control Loop Sequence
A feedback control system operates as follows:
- (B) Error detection: Measures deviation from the desired state.
- (C) Controller: Processes the error and adjusts the actuator.
- (A) Actuator: Applies adjustment to the system.
- (D) Feedback sensor: Detects the system’s state and provides feedback to the controller.
Step 2: Conclusion The correct sequence is (B), (C), (A), (D). Final Answer: \[ \boxed{(B), (C), (A), (D)}\]
