A closed-loop control system with negative unity feedback has a loop transfer function
Chapter 0, Problem P5.19(choose chapter or problem)
A closed-loop control system with negative unity feedback has a loop transfer function L{s) = Gc(s)G(s) = s(s2 + 6s + 12) (a) Determine the closed-loop transfer function T(s). (b) Determine a second-order approximation for T(s). (c) Plot the response of T(s) and the secondorder approximation to a unit step input and compare the results.
