Unformatted text preview: s = . . Characteristic equation • From the above transfer function, one can obtain the characteristic equation using the denominator. • The characteristic equation is used to solve the root of a second order system • The root can determine the speed of response and damping 60 5.7 60 = 2ξ 5.7 0 0 • There are three cases for the roots: - Case 1 ξ - Case 2 ξ - Case 3 ξ ξ 1 when ξ >1 called over damped when ξ =1 called critical damped 1 ξ when ξ 1 called underdamped - How does the system respond to a unit...
