Question 1 a-d a. Using root-locus techniques, design the lead compensator (fmd a, b, and K of D(s)) so that the system is stable and the dominant poles of the closed-loop transfer function are at s = —6 ± 4j. The design is not unique. b. What is the steady-state error to a unit-step reference input using your design? c. Estimate the dynamics using your design (4, 4. MR) d. Plot the step response using your design withISialgh indicating 4. 4, and 4.
