- Problem 3 25p Design A Lag Compensator So That The System Given In The Figure Below Where K S 4 G S S 2 S 1 (170.69 KiB) Viewed 30 times
Problem-3 (25p). Design a lag compensator so that the system given in the figure below, where K(s + 4) G(s) = (s+ 2) (s + 6) (s+8) R(S) C(s) operates with a steady-state error of ess = 0.02 and a 15% G(s) overshoot (corresponds to a damping ratio of 3 = 0.517 and a phase margin of 53°). Notes: Please draw Bode plots by hand neatly and clearly on the blank semi-logarithmic planes provided below (you may change the limit values of the axes if needed). Please write the transfer function of the lag compensator separately after the design process for clarity.
