Unformatted text preview: : Given : . The position control system uses unity feedback. Find : A lead compensator (with gain) so that the resulting closed-loop system satisfies the following specifications: (i) steady-state error to unit ramp input ≤ 0.04 (ii) phase margin ≥ 45 ° . PROBLEM 3 : Given : Find : (a) Compensator G c (s) for and 45 ° < PM < 46 ° (b) Unit step and unit ramp responses Y(s) R(s) + G c (s) −...
