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: Apply the steady-state error formula.
For a unit step input, the steady-state error is determined by the final value theorem or by evaluating the system's response at its steady state.

Step 2: State the conclusion.
The steady-state error for the system is calculated to be 0.4, thus option (C) is the correct selection.
