Steady-State Error
Using steady-state error analysis, determine e_ss, for a Type 0 Unit Step input.
Hint

Searching for "Steady-state error analysis" in the FE handbook used during the exam, you'll find the below table:

where
$$T$$
denotes the type of system, i.e., type 0, type 1, etc.
The corresponding value associated with the "Unit Step" input and Type 0 is:
$$$e_{ss}=\frac{1}{(K_B+1)}$$$
$$$e_{ss}=\frac{1}{(K_B+1)}$$$
