A first-order element under control is combined with a proportional controller. The closed-loop process control transfer function is: PV/R = 0.68/ (1+1.55s). What is the time-domain response of this closed-loop process to a unit step at the input? After you find the response, calculate the final value of the process variable using the final value theorem.
