Based on the requirements, where should the dominant poles be located on the s- located at-am ± plane? (hint: for a second order system the dominant poles are Jod) b. The closed-loop poles of the system are located at-1.25 ± J2.86 at a gain of K 102.47 to meet the = needed: lead, lag or lead-lag? Why? 0.4 requirement. What type of compensator is . c. Th e compensator designer has decided to place the zero of the compensator at e 4.5. What is the required angle of the compensator pole, Pe Where should the pole be located on the real axis? What is the transfer function of the compensator? d. e.
