Skill-Assessment Exercise 9.3 PROBLEM: A unity feedback syApagorwPREnEnhancer K G(s) s(s+7) is operating with a closed-loop step response that has 20% overshoot. Do the following: a. Evaluate the settling time. b. Evaluate the steady-state error for a unit ramp input. c. Design a lag-lead compensator to decrease the settling time by 2 times and decrease the steady-state error for a unit ramp input by 10 times. Place the lead zero at -3. ANSWERS: a. T, = 1.143 s b. Cramp (0)=0.1189 c. Ge(s) = (s+3)(s+0.092) (s+9.61) (s+0.01)' K = 205.4 The complete solution is at www.wiley.com/college/nise. Wiley PLUS WPCS Control Solutions
