Unformatted text preview: ise controller with a system transfer function G(s), reference input R(s), gain K, disturbance Fhill(s), and output Y(s) is shown below. a. Show that the output Homework 2 Page 7 of 9 Dr. S Bergbreiter ENME 462 Vibrations, Controls and Optimization II Spring 2010 b. Calculate the transfer function Y(s)/R(s) assuming that Fhill(s) = 0 and Y(s)/Fhill(s) assuming that R(s) = 0. c. A closed loop cruise control system is pictured below. Find an expression for the output Y(s). d. Repeat part (b) for the closed loop system. e. How would you minimize the disturbance provided by the hill while still following the reference input R? If K is large, Y/R approaches 1 and Y/Fhill approaches 0 5. Problem 2.23 in Nise (Control Systems Engineering, 5th Edition).
