Question: The following transfer functions are the forward transfer function G(s) and the feedback transfer function H(s) for a system whose closed-loop transfer function is G

The following transfer functions are the forward transfer function G(s) and the feedback transfer function H(s) for a system whose closed-loop transfer function is
G (s) / 1 + G (s) H (s)
For each case determine the system type number, the static position and velocity coefficients, and the steady-state errors for unit-step and unit-ramp inputs.
a. G (s) H (s) = 20/s
b. G (s) H (s) = 20 / 5s + 1
c. G (s) H (s) = 7 / s2
