Question

The Block diagram for a control system is shown below: 

• A. 0.2
• B. 0.3
• C. 0.4
• D. 0.5

Hint:

The steady-state error for a unit step input is determined by the open-loop transfer function and system type.

Answer 1

The Correct Option is C

Step 1: Use the steady-state error formula for a control system.
For a unit step change in the input, the steady-state error can be found by applying the final value theorem or evaluating the system's response at steady state.

Step 2: Conclusion.
The steady-state error for the given system is 0.4, so the correct answer is (C).
