E4.6 A feedback system has the closed-loop transfer function given by

s+ps + 10 T(s) == s3+2ps+4s+(3-p)

Compute the sensitivity of the closed-loop transfer function to changes in the parameter p, where p 7 0.
Compute the steady-state error to a unit step input as a function of the parameter p.

s+ps + 10 T(s) == s3+2ps+4s+(3-p)
